OVERLOADING IN JAVA
2 type of overloading
1. method overriding
 Providing multiple implemention of  any method  inside  the same class is called  as overloading.
2. constructor overloading
 Providing multiple implemention of  any constructor  inside  the same class is called  as constructor overloading.
 NOTE

•    overloading can be performed by only change the number of argu,data type and number of order 
• method overloading is implementing polymorphysm in java.

 example
 // overloaded methhod
  class sum
{
   int a;
 int b;
  sum()
{
  
} 
  sum(int a,int b)
{
   this.a=a;
this.b=b;
}
   public void add(int a,int b)
 {
    System.out.println("sum of  "+a+" and "+b+" : "+(a+b));
  } 
   // overloaded methhod
    public void add(float a,float b)
 {
    
   System.out.println("sum of  "+a+" and "+b+" : "+(a+b));
  }
  // overloaded methhod
   public void add(int a,int b,int c)
 {
    
   System.out.println("sum of  "+a+" ,c "+ +" and "+c+" : "+(a+b+c));
  }
