Java 中的 NumberFormat 等于()方法,示例

原文:https://www . geesforgeks . org/number format-equals-method-in-Java-with-examples/

equals() 方法是Java . text . number format的内置方法,接受一个作为对象的参数,如果这个参数对象与对象相同,则返回 true,否则返回 false。

语法 :

public boolean equals(Object arg)

参数:该函数接受单个强制参数参数,该参数指定要比较的对象。

返回值:该函数返回一个布尔值。如果两个对象相同,则返回 true,否则返回 false。

下面是上述功能的实现:

程序 1:

// Java program to implement
// the above function
import java.text.NumberFormat;

public class Main {
    public static void main(String[] args)
        throws Exception
    {

        // Get the Currency Instance
        NumberFormat nF1
            = NumberFormat
                  .getCurrencyInstance();

        // Get the Currency Instance
        NumberFormat nF2
            = NumberFormat
                  .getCurrencyInstance();

        // Check if equal or not
        if (nF1.equals(nF2))
            System.out.println("Yes both are equal");
        else
            System.out.println("Yes both are not equal");
    }
}

输出:

Yes both are equal

程序二:

// Java program to implement
// the above function
import java.text.NumberFormat;

public class Main {
    public static void main(String[] args)
        throws Exception
    {

        // Get the Currency Instance
        NumberFormat nF1
            = NumberFormat
                  .getCurrencyInstance();

        // Get the Instance
        NumberFormat nF2
            = NumberFormat
                  .getInstance();

        // Check if equal or not
        if (nF1.equals(nF2))
            System.out.println("Yes both are equal");
        else
            System.out.println("both are not equal");
    }
}

输出:

both are not equal
