A static block is a code block defined with the 'static' keyword and is not inside others blocks.
The static block is executed when the class is first loaded and the main purpose is perform all the initialization that may not be appropriate inside a constructor.
Static blocks and static methods in java are two types of class-level elements used for defining behavior that is associated with the class itself rather than the individual objects of the class. Therefore these both are executed at class-level, but there are some differences between the two. Static blocks in Java are defined using the 'static' keyword and are executed only once when the class is loaded into the memory. They are used for initializing static variables or performing tasks that must be done only once, like reading configuration files or setting up a database connection. Static block is executed once when the class is loaded into the java virtual machine. It is used for initializing the static variables or performing any other one-time setup that needs to happen before the class can be used. A static block can be used to read configuration files or for initializing the static variables that depend on some external factors. Below is the syntax of a static block Public class NinjaClass{ static{ //code } } A static method is defined using the static keyword, which is then followed by the method signature and method body. Static methods cannot access other static variables or methods of the class directly. It is a method associated with the class instead of individual class objects. They can be called on the class itself instead of on an instance of the class. For accessing non-static variables or methods, we need to create an instance of the class and use that instance to access the non-static members. Below is the syntax of static method: Public class NinjaClass{ Static void SaticMethod(){ //code } } Due to the order in which Java initializes its classes, static blocks are executed before static methods. Static blocks are executed before any other code in the class when a Java class is loaded into the memory. Therefore, static variables that are initialized in the static block will be initialized before any static methods are called.Java ensures that static variables are initialized before any other code in the class is executed. Static methods can be called and executed once the static variables are initialized. Therefore, Java developers need to understand the order in which static methods are executed for writing efficient code. In a class, static methods are executed in the order they appear. The execution depends on the order in which they are defined when the JVM loads a class. Static initializers are executed before any static method in the class.
'global static'?! There is no such thing.
Shortly, you can not.Different approaches are however available.1. Put your non static method in different class. Then call it from your static content by first instantiating the class.2. Make a duplicate static method for your non static method and use from your static content.

Static Frequency converter is a static device with power electronic component such as scrs etc
Class Ram { static {} //static block to execute something before main method Ram() //constructor {} {} //init block public static void main(String ss[]) { } other methods }
A static identifier in a block has execution time lifespan, i.e. its value persists from point of initialization to program termination.A static identifier outside of any block has execution time lifespan, because of its non-block semantics, but the static attribute takes on a different meaning, and means that it is not visible to modules outside of the file it is defined in.(Only applicable to C++ - answer provided for completeness sake) A static identifier in a class is common to all instances of that class. A static method of a class can access only static identifiers of that class.
A static variable in C is one in which the memory is preallocated before the execution unit begins and lasts for the entire program unit.A non-static variable in C will be allocated in the block in which it is contained, and destroyed outside that block.

mgsin (theta) - (static) mu * mgcos(theta) = 0 rearrange the equation and cancal mg therefore, tan ( theta) = mu (static) theta = arctan (static mu) If the static coefficient is 0.57, then theta = arctan (0.57) theta = 29.7 degree Note: from the equation, the mass of the block is independent to the angle. Whether you have a bigger block or smaller block, it will start sliding @ 29.7 degree.
By using the static block
initialize static variables are stored in data segment where uninitialized static variables are stored in BSS(block storing for Symbol) it also a part of data segment exp static int i=10;//stored in data segment static int i;//stored in BSS (uninitialized data segment) Thanks NAvin
static shielding bags resist tribocharging AND block strikes of electrostatic discharge (ESD). static-resistant bags are technically-speaking "anti-static", meaning they resist tribocharging. Static-resistant bags DO NOT block ESD strikes. Most people have issues because they use anti static bags to ship hard drives. Hard drives should be handled using static shielding bags. Humans create thousands of volts, whereas a hard drive can be damaged with hundreds of volts. You can't feel the first several thousand volts, so people using anti static bags are unaware anything is happening.
One example of static friction is the inability to push a car parked down the street. Another example is a block on an inclined table that does not slide. Last example is the pushing of a couch. Static friction is provided by the slippers which allows for gripping the floor.
Static friction does not apply when the block is already moving. Without friction, the force on the block parallel to the surface of the incline is Fg*sin(angle), so the acceleration without friction is 9.8* sin(30) = 9.8 * (1/2) = 4.9 Since it is accelerating at 3.2, friction is slowing down the block by (4.9-3.2 = 1.7). The coefficient of kinetic friction is (1.7/4.9) = 0.346939
A static variable has load module lifetime. Its value persists until changed or the program exits. If the variable is at file scope, i.e. outside of any block, the word static means that it is visible only to code within that compilation unit, i.e. it can not be linked by other compilation units. In a C++ class, a static variable is common to all instances of the class.
In order for the block to move the force applied has to be greater than the maximum force of static friction. F > fs fs = coefficient of friction * normal force = .65 * 36N // you can use the weight for the normal force since the block is being supported = 23.4N Since applied force of 42N is greater than the 23.4N due to friction, the block will start sliding, where kinetic friction will act on the block.
