class MyClass {
// Declare a static method to return the square of a number.
public static int getSquare(final int n) {
return n*n;
}
public static void main(String[] args) {
// Call the static method to find 1522
System.out.println( MyClass.getSquare(152) );
}
}
yes we can call a static method with object
Yes, it is possible to call a static method from a non-static method. However, it is not possible to call a non-static method from a static method without first having an instance to operate on.
No
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.
I assume the question is about Java. How you call a method from inside the main method depends on whether this is an instance method or a static method. To call an instance method, you need to have a valid instance. Say foo is an instance of class Foo, which was created inside the main method. Then to call the instance method implode() use foo.implode() To call the static method bar() of class Foo, use Foo.bar().
if some method is static, then you can not call that method through the oobject of that class. but the name of the class. let us see a example: class Test { int a; int b; static void show() { System.out.println("we are in show"); } } class Main { public static void main(String args[]) { Test t=new Test(); t.show();\\thiss is an erroraneous code. because, the method "show()" is static. Test.show();\\this is correct } Arnas Sinha
The main method is static because the JVM would be invoking this method as the starting point of execution. If this is like other normal methods, the JVM would have to instantiate an object of the class before it can call it. This is not possible because this is the starting point. If the main method is static the JVM can directly call this by specifying the class name.
No, the reason is simple: A method marked as a static means, that you don't need create an instance (create an object with the 'new' operator) in order to use it. The main method is the entry point for a java application, therefor there is nothing after you call it. no one who can create an object of the type of your class and call the main method. So the jvm must call the main method with no object reference.
Yes, we can access all methods which declare with static means then we can access.. ex: class s{ static method() { System.out.println("Welcome"); } } class fun{ public static void main(String args[]) { method(); } }
No. Static methods are invoked by using the name of the class instead of the name of an instance of a class. Example: public class Test { public static void methodA { // do something ... } public void methodB { // do something else ... } } A program could use methodA by simply calling it using the class name: // call the static method Test.methodA(); To use methodB(), a program would have to first create an instance of the class then call the method: // call the non-static method Test t = new Test(); t.methodB(); Note that you can call methodA from the instance: // call the static method Test t = new Test(); t.methodA(); However, this is considered bad practice. And you cannot call methodB at all using the class name: // can't do this - compile error Test.methodB();
Yes, a static method may be overloaded.
Static is a keyword which is used to call the methods or variables without creation of that class object. It will directly calls the respective method and varialbles.
