SDET Interview questions: How to access methods of a class in Java?

There are two ways to access method in class.

1. By creating object of class

2. Using static : If we use static then we can access the method without creating object of the class

Example of By creating object of class:

public class configReader {

public int methodtwo(int a, int b)

// int is return type and public is access modifier. int a and int b are input parameters

{
    int sum = a+ b;
    return sum;

}

public static void main(String[] args) {

    configReader md = new configReader(); //Object Creation
    int result = md.methodtwo(2,3);               // access method by using object
    System.out.println(result);
}

}

Example of accessing method with Static:

public class configReader {

public static int methodone(int a, int b) {

//static has been used so that with class name we can access the method

    int sum = a+ b;
    return sum;
}

public static void main(String[] args) {
    int resultone = methodone(3,4);            //accessing method directly without object

System.out.println(resultone );

}
}

If we want to access the same method in another class then use classname:

configReader.methodone(3,4)
