Question:


Find the output of the following snippet:



String S1 = "AB", S2 = "BC";

for(int i = 0, j = 0; i < S1.length(); i++, j++)
{
    System.out.println(S1.charAt(i) + S2.charAt(j));
}

Accepted Answer

Answer:


131
133


Explanation:


The loop runs for:



S1.length() = 2



So there will be 2 iterations.


Character ASCII Values:


'A' = 65
'B' = 66
'C' = 67


First Iteration:


S1.charAt(0) = 'A'
S2.charAt(0) = 'B'



ASCII addition:



65 + 66 = 131



Output:



131


Second Iteration:


S1.charAt(1) = 'B'
S2.charAt(1) = 'C'



ASCII addition:



66 + 67 = 133



Output:



133


Important Concept:


    
        charAt() returns characters
    

    
        When characters are added using +,
        Java adds their ASCII values
    

    
        Therefore, numeric output is produced instead of string concatenation
    


Final Output:


131
133
