Question

Give the output of the following program segment and specify how many times the loop is executed.

String s = “JAVA”;
for(i=0;i<s.length();i+=2)
System.out.println(s.substring(i));

Answer 1

JAVA
VA

Loop executes for 2 times.

Explanation:

The string “JAVA” has a length of 4. Since the loop variable increases by 2 each time, the loop runs twice. The substring(i) method extracts the string from index i to the end. As i takes the values 0 and 2, the substrings obtained are “JAVA” and “VA”.
