Pseudo Java code:

public static void main(String[] args) {
    System.out.print("Enter two numbers: ");
    int x = read();
    int y = read();
    print(x / y);
}

JD-GUI output:

public static void main(String[] paramArrayOfString)
{
  paramArrayOfString = 0;
  int i = 0;
  break label91;
  int j = returnAddress;
}

Fernflower output:

   public static void main(String[] param0) {
      // $FF: Couldn't be decompiled
   }

JAD output:

    public static void main(String args[])

        if(0 - i1 != 0)
            break MISSING_BLOCK_LABEL_59;
        l;
        JVM INSTR ret 10;
        local;
        l;
        i1;
        j1;
