Java Output Functions

Introduction of Java Output Function (System.out.println())

Java use print function to display out. It can be used in two way.

1. Output without new line

   For this purpose we use
   System.out.print('desired output string');
   

2. Output with new line

   For this purpose we use
   System.out.println('desired output string');
   

3. Example :

Save this file with Test.java

class CRectangle
 {
  private int length;
  private int breadth;
  
  CRectangle()
  {
   System.out.println("Class CRectangle : Default constructor called...");
   length = 5;
   breadth = 3;
  }
  
  CRectangle(int l, int b)
  {
   System.out.println("Class CRectangle : Parametrized constructor called..");
   length = l;
   breadth = b;
  }
  
  void setLength(int l){length = l;}
  int getLength(){return length;}
  
  void setBreadth(int b){breadth = b;}
  int getBreadth(){return breadth;} 
}

import java.io.*;
class Test
{
 public static void main(String args[])
 {
  CRectangle r;
  r = new CRectangle();
  System.out.println("Length  : " + r.getLength());
  System.out.println("Breadth : " + r.getBreadth());
 }
}
