Java Character equals()方法及示例

java.lang.Character.equals() 是Java中的一个函数，它将此对象与指定对象进行比较。如果参数不为空，那么结果为真，是一个代表与此对象相同的char值的Character对象。

语法

public boolean equals(Object obj)

参数： 该函数接受一个单一的参数obj，指定要比较的对象。

返回值： 该函数返回一个布尔值。如果对象相同，则返回真，否则，返回假。

下面的程序说明了上述方法。

程序1 :

// Java program to demonstrate the function
// Character.equals() when two objects are same
import 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);
    }
}

输出:

Z and Z are equal is true

程序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);
    }
}

输出:
