String Example : String Reverser

The reverse() method in the following program follows that idea. The variable j indexes characters in the original string starting at the rightmost character, data.length()-1, and moves left until it reaches the first character. Each character is appended on the right of a new String.
public class ReverseTester
{

public static String reverse( String data )
{
String rev = new String();

for ( int j=data.length()-1; j >= 0; j-- )
rev += data.charAt(j);

return rev;
}

public static void main ( String[] args )
{
System.out.println( reverse( "Hello" ) );
}
}
