How to convert an integer value to string?

Question

How do I convert an integer variable to a string variable in Java?

Answer 1

you can either use

String.valueOf(intVarable)

or

Integer.toString(intVarable)

Answer 2

There are at least three ways to do it. Two have already been pointed out:

String s = String.valueOf(i);

String s = Integer.toString(i);

Another more concise way is:

String s = "" + i;

See it working online: ideone

This is particularly useful if the reason you are converting the integer to a string is in order to concatenate it to another string, as it means you can omit the explicit conversion:

System.out.println("The value of i is: " + i);

Answer 3

Here is the method manually convert the int to String value.Anyone correct me if i did wrong.

/**
 * @param a
 * @return
 */
private String convertToString(int a) {

    int c;
    char m;
    StringBuilder ans = new StringBuilder();
    // convert the String to int
    while (a > 0) {
        c = a % 10;
        a = a / 10;
        m = (char) ('0' + c);
        ans.append(m);
    }
    return ans.reverse().toString();
}
