Java中的 NumberFormat equals() 方法及示例
equals()方法是Java.text.NumberFormat的内置方法,它接受一个对象参数,如果该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:该函数接受一个强制参数arg ,该参数指定要与之比较的对象。
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。
下面是上述函数的实现:
方案一:
// 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
方案二:
// 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
