String

I am writing a program, to add certain number of COMMAs with a string but I am not getting my desire result, it is just showing a single COMMA "," instand of "ABCD,,,". I don,t know why input=input+","; is not working correctly.

String input;
input = "ABCD"
for(int i=0 ; i<3; i++); {
    input = input + ",";
    }
println (input);

Your issue is not with commas, but with semicolons. Specifically, you have one where you shouldn't and don't have one where you should.

String input;
input = "ABCD";
for(int i=0 ; i<3; i++) {
    input = input + ",";
    }
println (input);
