What is the difference between java static methods and instance methods

1. When calling a static method externally, you can use class name.method name or object name.method name. Instance methods only have the second method.

You can call static methods without creating an object.

2. When using static method class members, only static members are allowed to be accessed, and instance member variables and instance methods are not allowed to be accessed. There are no restrictions on instance methods.

Example

public class staticMethodTest {
void nonStaticMethod() {
System.out.println("This is a non static method");
}
static void staticMethod(staticMethodTest s) {
System.out.println("This is a static method");
s.nonStaticMethod();
}
public static void main(String[] args) {
staticMethodTest obj=new staticMethodTest();
staticMethod(obj);
}
}
