first u have to input the string and then substitute the uppercase character by lower case character and vice versa.
here is the program

// !! RAM !!

import java.io.BufferedReader;
import java.io.*;

public class converter
{
public static void main( String[] a )
{
try{
BufferedReader d = new BufferedReader( new InputStreamReader(System.in ));

String input;
System.out.println( " enter string " );
input = d.readLine();
String output="";

for( int i=0;i< input.length();i++)

{
if( Character.isLowerCase( input.charAt(i) ) )
output += Character.toUpperCase( input.charAt(i) );
else
output += Character.toLowerCase( input.charAt(i) );
}
input = output;
System.out.println( " ur string is::"+ input );
}
catch( IOException e)
{
System.out.println(" IOException throwed ");
}
}
}
