is the function same as method in java

In Java, a method is a block of code that performs a specific task and is defined within a class. A function is a block of code that performs a specific task and is defined outside of a class.

In Java, methods and functions are similar in that they both contain a block of code that can be called and executed by other parts of the program. However, there are some differences between methods and functions in Java:

• Scope: Methods are defined within a class and have access to the variables and other members of that class, while functions are defined outside of a class and do not have access to the variables and members of any particular class.

• Declaration: Methods are declared within a class using the public, private, or protected access modifiers and a return type, while functions are declared outside of a class using a return type and the static modifier.

• Invocation: Methods are invoked on an instance of a class using the . operator, while functions are invoked by their name.

Here is an example of a method in Java:

public class MyClass {
    public void sayHello() {
        System.out.println("Hello, World!");
    }
}

This method, sayHello, is defined within the MyClass class and can be invoked on an instance of MyClass like this:

MyClass myObject = new MyClass();
myObject.sayHello();

Here is an example of a function in Java:

public static int add(int x, int y) {
    return x + y;
}

This function, add, is defined outside of any class and can be invoked by its name like this:

int result = add(3, 4);

For more information on methods and functions in Java, you can refer to the Java documentation or other online resources.
