Sir sorry my doubt might be silly, but I want to ask
When we use just string we use concat & when we use stringBuffer we use Append..
Why can't we use concat method only?

[shivankgarg]

x = x.concat(y);
System.out.print(x);
Output :ABCTECH
You had not stored the value of concatenated string in any variable that's why it was not getting concatenated
