java.lang.Character compareTo(Character anotherCharacter)
Description
The compareTo(Character anotherCharacter) java method compares two Character objects numerically.Don’t get confused on the usage of this method to that of the compare() method. The compareTo() method is used to compare two Character object while the compare() method is used primarily to compare two character primitive. But since autoboxing and unboxing features are already available in java starting at java 1.5, you can easily used this two method regardless if its primitive or an object.
Important Notes:
- Specified by compareTo in interface Comparable<Character>
Method Syntax
public int compareTo(Character anotherCharacter)
Method Argument
| Data Type | Parameter | Description |
|---|---|---|
| Character | anotherCharacter | the Character to be compared. |
Method Returns
The compare(char x, char y) method of Character class returns the value 0 if x == y; a value less than 0 if x < y; and a value greater than 0 if x > y.
Compatibility
Requires Java 1.2 and up
Java Character compareTo(Character anotherCharacter) Example
Below is a simple java example on the usage of compareTo(Character anotherCharacter) method of Character class.
package com.javatutorialhq.java.examples;
/*
* This example source code demonstrates the use of
* compareTo(Character anotherCharacter) method of Character class.
*/
public class CharacterCompareToExample {
public static void main(String[] args) {
// initialize 3 Byte object
Character firstValue = new Character('c');
Character secondValue = new Character('a');
Character thirdValue = new Character('c');
// compare the first char to the second
int compareOneTwo = firstValue.compareTo(secondValue);
// compare the first char to the third
int compareOneThree = firstValue.compareTo(thirdValue);
// display the comparison result of first
// and second value
if (compareOneTwo == 0) {
System.out.println("First and second value are equal");
} else if (compareOneTwo > 0) {
System.out.println("First value is greater than second value");
} else {
System.out.println("First value is less than second value");
}
// display the comparison result of first
// and third value
if (compareOneThree == 0) {
System.out.println("First and third value are equal");
} else if (compareOneTwo > 0) {
System.out.println("First value is greater than third value");
} else {
System.out.println("First value is less than third value");
}
}
}
