Java Program
import java.io.*;
class sum
{
int a,b;
double c,d;
String s1,s2;
sum()
{
a=100;b=200;
}
sum(double x1,double y1)
{
c=x1;d=y1;
}
sum(String m, String n)
{
s1=m;
s2=n;
}
}
class overloading
{
int a,b,is;
double x,y,ds;
String c1,c2,ss;
int add(int a,int b)
{
is=a+b;
return is;
}
double add(double x,double y)
{
ds=x+y;
return ds;
}
void add(String ch1,String ch2)
{
ss=ch1+ch2;
System.out.println("Sum of 2 strings:"+ss);
}
}
class Demo
{
public static void main(String args[])
{
sum S1=new sum();
System.out.println("Value of first constructor="+S1.a+", "+S1.b+"n");
sum S2=new sum(1.3,2.7);
System.out.println("Value of Second constructor="+S2.c+", "+S2.d+"n");
sum S3=new sum("RABI","NS");
System.out.println("Value of Third constructor="+S3.s1+" ,"+S3.s2+"n");
overloading o1=new overloading();
o1.a1=o1.add(S1.a,S1.b);
o1.a2=o1.add(S2.c,S2.d);
o1.add(S3.s1,S3.s2);
System.out.println("Sum of 2 integers:"+o1.is);
System.out.println("Sum of 2 floating numbers:"+o1.ds);
}
}
Observed output:
Value of first constructor=100, 200
Value of first constructor=1.3, 2.7
Value of first constructor=RABI ,NS
Sum of 2 strings:RABINS
Sum of 2 integers:300
Sum of 2 floating numbers:3.0
