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.

This works for me. Simply to identify whether a String is a primitive or a number.

private boolean isPrimitive(String value){
        boolean status=true;
        if(value.length()<1)
            return false;
        for(int i = 0;i
