The java.lang.Character.equals() is a function in Java which compares this object against the specified object. If the argument is not null then the result is true and is a Character object that represents the same char value as this object.
Syntax:
public boolean equals(Object obj)
Parameters: The function accepts a single parameter obj which specifies the object to be compared with.
Return Value: The function returns a boolean value. It returns true if the objects are same, otherwise, it returns false.
Below programs illustrates the above method:
Program 1:
// Java program to demonstrate the function// Character.equals() when two objects are sameimport java.lang.*; public class gfg { public static void main(String[] args) { // assign values to c1, c2 Character c1 = new Character('Z'); Character c2 = new Character('Z'); // assign the result of equals method on c1, c2 to res boolean res = c1.equals(c2); // print res value System.out.println(c1 + " and " + c2 + " are equal is " + res); }} |
Output:
Z and Z are equal is true
Program 2:
// Java program to demonstrate function// when two objects are different import java.lang.*; public class gfg { public static void main(String[] args) { // assign values to c1, c2 Character c1 = new Character('a'); Character c2 = new Character('A'); // assign the result of equals // method on c1, c2 to res boolean res = c1.equals(c2); // prints the res value System.out.println(c1 + " and " + c2 + " are equal is " + res); }} |
Output:
a and A are equal is false
