Question

I Want to store the reversed string a in b without any function.

public static void main(String args[])
{

  BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
  String a=br.readLine();
  String b;
  for(int x=0,y=a.length()-1;x<a.length();x++,y--)
  {
             b.charAt(x)=a.charAt(y);
  }

But I get this error :

                   b.charAt(x)=a.charAt(y);
                           ^

required: variable

found: value

1 error

Can you explain it and help me fix it ?

Answer 1

You could just do

String a = "hello"; // the String to be reversed
String b = ""; // the String to store the reversed String
for (int i = a.length()-1; i >= 0; i--) {
    b = b+a.charAt(i);
}
