How to Solve Output Questions Fast (ICSE Strategy)

• Always write values of variables step-by-step.
• Understand operator precedence (++, --, %, /).
• In loops, track loop counter and condition carefully.
• For String functions, learn substring(), indexOf(), length().
• For arrays, track index positions properly.

Top ICSE Output Questions (Solved)

Output Question 1 (Loop)

class Test {
  public static void main(String args[]) {
    int i;
    for(i = 1; i <= 5; i++) {
      System.out.print(i*i + " ");
    }
  }
}
    

Output Question 2 (If-Else)

class Test {
  public static void main(String args[]) {
    int x = 10, y = 5;
    if(x > y)
      System.out.print(x - y);
    else
      System.out.print(x + y);
  }
}
    

Output Question 3 (While Loop)

class Test {
  public static void main(String args[]) {
    int a = 1;
    while(a <= 5) {
      System.out.print(a + " ");
      a = a + 2;
    }
  }
}
    

Output Question 4 (String Functions)

class Test {
  public static void main(String args[]) {
    String s = "COMPUTER";
    System.out.print(s.substring(1,4));
  }
}
    

Output Question 5 (Array)

class Test {
  public static void main(String args[]) {
    int a[] = {5, 10, 15, 20};
    System.out.print(a[2] + a[0]);
  }
}
    

Output Question 6 (Nested Loop)

class Test {
  public static void main(String args[]) {
    int i, j;
    for(i=1; i<=3; i++) {
      for(j=1; j<=2; j++) {
        System.out.print(i);
      }
      System.out.print(" ");
    }
  }
}
    

Common Mistakes Students Make in Output Questions

• Ignoring brackets in expressions
