"\r" is what you're looking for. System.out.print("\rZipping file " ...

as your class isn't static, retain the argument 'display text' globally within the constuctor, and then :

import java.io.*;

public class ProgressStatus {

    private short currentPercentage ;
    private short newpPercentage ;
    private String displayText;

    public ProgressStatus(String displayText) {
        this.displayText = displayText;
        currentPercentage = 0 ;
        System.out.flush() ;
    }

    public void updateProgress(long current, long total) {
        newpPercentage = (short)((float)current/total*100) ;
        if (newpPercentage != currentPercentage) {
            //Update the new %
            System.out.print("\r" + displayText + newpPercentage + "%") ;
            //Update the Internal
            currentPercentage = newpPercentage ;
            System.out.flush() ;
        }
    }
}

the "\r" returns the cursor to the start of the current line, therefore
each updateProgress(long current, long total) call fully overwrites the 
complete diplayed text on the current line of the console

hope this helps...
