Give the output of the following Java program segment:
String a[] = {"Atasi", "Aditi", "Anant", "Amit", "Ahana"};
System.out.println(a[1].charAt(1) + "*" + a[2].charAt(2));
The output of the above statement is:
Give the output of the following Java program segment:
String a[] = {"Atasi", "Aditi", "Anant", "Amit", "Ahana"};
System.out.println(a[1].charAt(1) + "*" + a[2].charAt(2));
The output of the above statement is:
Show Hint
- da
- d * a
- ti
- t * i
The Correct Option is B
Solution and Explanation
The array is: \[ \texttt{a[ ] = \{"Atasi", "Aditi", "Anant", "Amit", "Ahana"\}} \] Now check the required positions: \[ \texttt{a[1] = "Aditi"} \] \[ \texttt{a[2] = "Anant"} \]
Step 2: Apply the \texttt{charAt()} method.
The expression uses: \[ \texttt{a[1].charAt(1)} \] In the word \texttt{"Aditi"}: \[ A = 0,\ d = 1,\ i = 2,\ t = 3,\ i = 4 \] So, \[ \texttt{a[1].charAt(1) = 'd'} \] Now: \[ \texttt{a[2].charAt(2)} \] In the word \texttt{"Anant"}: \[ A = 0,\ n = 1,\ a = 2,\ n = 3,\ t = 4 \] So, \[ \texttt{a[2].charAt(2) = 'a'} \]
Step 3: Combine the output.
The complete statement is: \[ \texttt{a[1].charAt(1) + "*" + a[2].charAt(2)} \] So it becomes: \[ \texttt{'d' + "*" + 'a'} \] This prints: \[ \texttt{d*a} \] In the given options, this corresponds to d * a.
Step 4: Conclusion.
Therefore, the output of the statement is d * a.
Final Answer:d * a.
