  1. How to compare two long values

Compare two long values

We can use the following two methods to compare two long type value.

  • int compareTo(Long anotherLong) compares two Long objects numerically.
  • boolean equals(Object obj) compares this object to the specified object.

compareTo(Long anotherLong) returns

ValueMeaning
0if this Long is equal to the argument Long;
less than 0if this Long is numerically less than the argument Long;
greater than 0if this Long is numerically greater than the argument Long.

The following code uses the compareTo(Long anotherLong) method to do the comparison.

public class Main {
  public static void main(String[] args) {
    Long long1 = new Long(12345L);
    Long long2 = new Long("12346");
    /* j a  va2  s  . c  om*/
    System.out.println(long1.compareTo(long2));
  }
}

The output:

If you just want to check the equality,

public class Main {
  public static void main(String[] args) {
    Long long1 = new Long(12345L);
    Long long2 = new Long("12346");
    /*from j a  va 2  s . c  om*/
    System.out.println(long1.equals(long2));
  }
}

The output:
