What's the best way to check if a String represents an integer in Java?

Question

I normally use the following idiom to check if a String can be converted to an integer.

public boolean isInteger( String input ) {
    try {
        Integer.

There is guava version:

import com.google.common.primitives.Ints;

Integer intValue = Ints.tryParse(stringValue);

It will return null instead of throwing an exception if it fails to parse string.
