Integer.compare()

java.lang.Integer

public static int compare(int first,int second)

The value 0 if first == second
The value less than 0 if first < second
the value greater than 0 if first > second


Example:-

public class LengthComparator implements Comparator<String>
{
public int compare(String first, String second)
{
return Integer.compare(first.length(),second.length());
}
}


Arrays.sort(strArray,new LengthComparator());
