Exercise - 4 (Methods)

Exercise - 4

a). Write a JAVA program to implement constructor overloading.

class Student
{
int height=167;
  int weight=78;
  String course="Intermediate";
  int rollno=225;
  Student()
  {
  System.out.println("Inside of the First Method");
  System.out.println("Height="+height+"CM");
  System.out.println("Weight="+weight+"KG");
  System.out.println("Course with year:"+course);
  System.out.println("Roll NO:"+rollno);
  }
  Student(double marks)
  {
  System.out.println("Inside of the Second Method");
  System.out.println("Marks percentage:"+marks);
  }
}
class Biodata
{
  public static void main(String args[])
  {
  Student s1=new Student();
  Student s2=new Student(92.56);
  }
}

b). Write a JAVA program implement method overloading.


class Details
{
  String name="Vivo-Y87";
  int storage=64;
  String cameratype="Dual Camera";
  public void performance(int ram)
{
System.out.println("Inside of the 1st Method.......");
  System.out.println("Name of the Mobile is:"+name);
  System.out.println("Internal Storage of the Mobile is:"+storage+"GB");
  System.out.println("Ram of the Mobile is:"+ram+"GB");
  System.out.println("Camera type of the Mobile is:"+cameratype);
  }
        public void performance(String os,double version)
        {
System.out.println("Inside of the 2nd Method....");
System.out.println("The os of the mobile is:"+os);
          System.out.println("Version of the mobile is:"+version);
        }
}
public class Mobile
{
public static void main(String args[])
  {
      System.out.println("The Mobile Details are:");
      Details d=new Details();
                  d.performance(8);
                  d.performance("Android",8.10);
  }
}
