How to compare generic types in Java?

April 20, 2021

To compare generic types in Java, use the compareTo method.

Make sure your generic type is defined as T extends Comparable, then you can use compareTo to compare objects of type T:

public class ComparingClass<T extends Comparable<T>> {

  public boolean compareTwoValues(T value1, T value2) {
    return value1.compareTo(value2) < 0;
  }
}
