here is an example to read and concatenate 2 string without using 3rd variable:

public class Demo {
    public static void main(String args[]) throws Exception  {
        InputStreamReader r=new InputStreamReader(System.in);     
        BufferedReader br = new BufferedReader(r);
        System.out.println("enter your first string");
        String str1 = br.readLine();
        System.out.println("enter your second string");
        String str2 = br.readLine();
        System.out.println("concatenated string is:" + str1 + str2);
    }
}
