java - number reversal program gives only the first digit in output instead of the whole number -

string s1; int a, b, c = 0; s1 = t1.gettext(); = integer.parseint(s1); while (a > 0) {     b = % 10;     c = c * 0 + b;     = / 10; } t2.settext("" + c); 

here t1,t2 text fields. please let me know did go wrong because getting first digit of number enter in output , not whole number.

your incrementation of c c = c * 0 + b; want multiply 10 instead of 0: c = c * 10 + b;
