Static members/methods are used as in helper classes say like Math. classes which helps other objects to utilize Strings or useful functions for which you do not need to create object but invoked using Class name. Example -> singleton objects are invoked using a static function.
Disadvantage -> Static members are part of class and thus remain in memory till application terminates and can't be ever garbage collected. Using excess of static members sometime predicts that you fail to design your product and trying to cop of with static / procedural programming. It denotes that object oriented design is compromised. This can result in memory over flow.
Yes. Using the method InetAddress.getByName( String name) for instance.
No, Java only allows a method to be defined within a class, not within another method.
yes we can run java program without using main. we can run program by declaring the variable static..
java exception
Java program without mainWe need a main method for executing a program.But YES we can write a program without using main() method.TRICK 1 of 2 :: while writing applets in java we don't use main... we use init() method instead.TRICK 2 of 2 :: using 'static' we can write a program whic will execute successfully and output the desired message on screen. Here it is :: class Mohit{ static { System.out.println("This java program has run without the main method"); System.exit(0); } } -->save the program as Mohit.java to compile::javac Mohit.java (in command prompt) to run ::java Mohit(command prompt) output will be ::This java program has run without the main methodWhoa!!!!! we are done.;)
Using toString() method
Use length() method. Example: "java".length();

Calling a method in Java is when you run code associated with a specific class, using the name of an instance object of a class, followed by the dot operator, followed by the name of the method, followed by the arguments of the method, enclosed in parentheses.

No, Java only allows a method to be defined within a class, not within another method.
In Java, a function is called a "method". In Java as well as other languages, a method is a function defined specifically for one class. In Java, this is the only way to define functions, therefore, all functions are methods.In Java, a function is called a "method".
