String arr[]= {"DELHI", "CHENNAI", "MUMBAI", "LUCKNOW", "JAIPUR"};

Answer:

Output of the above code is:

false
JAI
  1. arr[0] is DELHI and arr[3] is LUCKNOW. Length of DELHI is 5 and LUCKNOW is 7. As 5 > 7 is false so the output is false.
  2. arr[4] is JAIPUR. arr[4].substring(0,3) extracts the characters from index 0 till index 2 of JAIPUR so JAI is the output.
