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" ) );
}
}
