Java ChoiceFormat equals()用法及代码示例

java.text.ChoiceFormat类的equals()方法用于在两个ChoiceFormat对象之间进行比较，并提供有关比较的布尔值。

用法:

public boolean equals(Object obj)

参数：此方法将obj作为参数，这是另一个ChoiceFormat对象用于比较。

返回值：如果两个选择格式对象都相等，则此方法返回true，否则返回false。

下面是说明equals()方法的示例：

示例1:

// Java program to demonstrate equals() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        // creating and initializing ChoiceFormat 
        ChoiceFormat cf1 
            = new ChoiceFormat( 
                "4#wed| 5#thu | 6#fri | 7#sat"); 
  
        // creating and initializing ChoiceFormat 
        ChoiceFormat cf2 
            = new ChoiceFormat( 
                "4#wed| 5#thu | 6#fri | 7#sat"); 
  
        // compare cf1 and cf2 
        // using equals() method 
        boolean status = cf1.equals(cf2); 
  
        // display the result 
        if (status) 
            System.out.println("Both ChoiceFormat"
                               + " objects are equal"); 
        else
            System.out.println("Both ChoiceFormat "
                               + "objects are not equal"); 
    } 
}

输出：

Both ChoiceFormat objects are equal

示例2:

// Java program to demonstrate equals() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        // creating and initializing ChoiceFormat 
        ChoiceFormat cf1 
            = new ChoiceFormat( 
                "1#sun| 2#mon | 3#tues | 4#wed"); 
  
        // creating and initializing ChoiceFormat 
        ChoiceFormat cf2 
            = new ChoiceFormat( 
                "4#wed| 5#thu | 6#fri | 7#sat"); 
  
        // compare cf1 and cf2 
        // using equals() method 
        boolean status = cf1.equals(cf2); 
  
        // display the result 
        if (status) 
            System.out.println("Both ChoiceFormat"
                               + " objects are equal"); 
        else
            System.out.println("Both ChoiceFormat "
                               + "objects are not equal"); 
    } 
}

输出：

Both ChoiceFormat objects are not equal
