Java Tutorial : Java Super Keyword (Invoke super-class constructor with parameter) 

SuperClass.java

public class SuperClass
{

    public SuperClass(String name)
    {
        System.out.println("Inside SuperClass(String name) constructor. ");
        System.out.println("name = "+name);     
    }
    
    public SuperClass(String name,int age)
    {
        System.out.println("Inside SuperClass(String name,int age) constructor. ");
        System.out.println("name = "+name);
        System.out.println("age = "+age);
    }

}

SubClass.java

public class SubClass extends SuperClass
{

    public SubClass(String name)
    {
        super(name);
        System.out.println("Inside SubClass(String name) constructor. ");
    }
    
    public SubClass(String name,int age)
    {
        super(name,age);
        System.out.println("Inside SubClass(String name,int age) constructor. ");
    }

}

SuperTest.java

public class SuperTest
{

    public static void main(String[] args)
    {
        SubClass subClassObj1 = new SubClass("Peter");
        System.out.println("--------------------------");
        SubClass subClassObj2 = new SubClass("John",30);
    }
}

Output

Inside SuperClass(String name) constructor. 
name = Peter
Inside SubClass(String name) constructor. 
--------------------------
Inside SuperClass(String name,int age) constructor. 
name = John
age = 30
Inside SubClass(String name,int age) constructor.
