java - return loop results for another method

Question

Its a loan calculator. I have a loop like

    public String loopresult(){
     for (int i=1; i<10; i++)
     return ((i) + "..........." + (i)*(i))
     }

It says this class must return String value. I tried

    valueOf.String((i) + "........" +(i)*(i)))

but didnt work.

I have to append it in txtArea.

    txtArea.append(loopresult())

what i want inside txtArea is like

2.........4 3.........9 so on, so it means this line will have int and string both.

Most likely what you intended was the following. You can only return one value, not multiple values. BTW You have a String already so your error message is confused.

 public String loopresult(){
     StringBuilder sb = new StringBuilder();
     for (int i=1; i<10; i++)
         sb.append(i + "..........." + i*i + "
");
     return sb.toString();
 }
