The java.lang.Double.compareTo() is a built-in method in java that compares two Double objects numerically. Then we define a comparator class AgeComparator that overrides the compare method to compare ages of two students and return appropriate values. It returns the result in integer equivalent value by comparing the two int method arguments. How To Compare … It returns -1 if this object’s price is less than another object’s price, 0 if the prices are equal, and 1 if this object’s price is greater than another object’s price. The syntax of CompareTo() method is as follows: int compareTo(T obj) In the above syntax, T signifies the type of objects you are going to compare. El método compareTo se usa para realizar una ordenación natural en una cadena. Returns zero if the first argument and second argument is equal. The result is a positive integer if this String object lexicographically follows the argument strin… The parameter ‘anotherInteger’ represents the Integer to be compared. Description. The suggested idiom for performing these comparisons is: (x.compareTo(y) 0), where is one of the six comparison operators. This method returns an integer value. This method compares two integer objects numerically. In this example, we will show you how to use Java 8 Lambda expression … The following examples show how to use java.math.BigInteger#compareTo() .These examples are extracted from open source projects. If a string 'str1' comes before another string 'str2' in dictionary, then str2 is said to be greater than 'str1' in string comparison.. string1 > string2 – ‘string1’ comes AFTER ‘string2’ in dictionary. package com.tutorialspoint; import java.lang. If x>y then the method returns value greater than 0. returns == 0 then the two strings are lexicographically equivalent. This method returns an integer value based on the result. Live Demo. The return type of Java compareTo() method is an integer and the syntax is given as: int compareTo(String str) In the above syntax, str is a String variable that is being compared to the invoking String. Return Value: The return value will be 0 if two dates are equal. For example, if the objects are Strings, then T is String.
