How to call methods between two classes
Create a class , And write method

public class Demo02{
    
    /** *  Calculate two int The sum of type integers  * @param a  Addition number  * @param b  Augend  * @return a + b  And  */
    public static int mySum(int a, int b){
    
        return a + b;
    }
}

Create another class , Call the method just written

public class Demo02Test {
    
    public static void main(String[] args) {
    
        int sum = Demo02.mySum(10, 20);
        System.out.println(sum);
    }
}
// Output results
