[love_angel69]

this is a class to determine the perfect numbers between 1 and 100..
public class Perfect {

public static void main(String[] args) {
// Perfect numbers

for ( int i=2; i<=1000; i++ )
{
int sum = 0;
for ( int j=1 ; j<i ; j++ )
{
if ( i % j == 0 )
{
sum = sum + j;
}
}
if ( sum == i )
{
System.out.println("" + i + " is a perfect number" );
System.out.print("Factors are: " );
for ( int f=1; f<i ; f++ )
{
if ( i % f == 0 )
{
System.out.print(" " + f );
}
}
System.out.println();
}
}
}
}

extend JApplet from your Perfect class.

  public Perfect() {}

  public void init() {
    try {
      jbInit();
      // hook up buttons
      this.ppnBtn.addActionListener(this);
      this.clearBtn.addActionListener(this);
    }
    catch (Exception e) {
      e.printStackTrace();
    }

        if (i % j == 0) {
          sum = sum + j;
        }
      }
      if (sum == i) {
        reportTA.append("" + i + " is a perfect number\n");
        reportTA.append("Factors are: ");
        for (int f = 1; f < i; f++) {
          if (i % f == 0) {
            reportTA.append(" " + f);
