public static void someStaticMethod() {
// some code
}
}
// When invoking in other class
public class Main {
public static void main(String[] args) {
// we can do the following
// use someMethod statically, i.e. without creating instance of
// SomeClassWithStaticMethod
SomeClassWithStaticMethod.someStaticMethod();
}
}
// normal class
public class NormalClass {
public void normalMethod() {
// code
}
}
// When invoking in Main
public class Main {
public static void main(String[] args) {
// we have to create instance of NormalClass
NormalClass normalClass = new NormalClass();
normalClass.normalMethod();
// we cant write NormalClass.normalMethod()
}
}
