Java中的 NumberFormat hashCode() 方法及示例
hashCode()方法是Java.text.NumberFormat的内置方法,它返回给定实例对象的哈希码值。
语法:
public int hashCode()
参数:该函数不接受任何参数。
返回值:该函数返回哈希码值。
下面是上述函数的实现:
方案一:
// Java program to implement
// the above function
import java.text.NumberFormat;
import java.util.Locale;
import java.util.Currency;
public class Main {
public static void main(String[] args)
throws Exception
{
// Get the instance for Locale US
NumberFormat nF
= NumberFormat
.getInstance(Locale.US);
// Prints the hash-code value
System.out.println("The hash-code values is: "
+ nF.hashCode());
}
}
输出:
The hash-code values is: 423132
方案二:
// Java program to implement
// the above function
import java.text.NumberFormat;
import java.util.Locale;
import java.util.Currency;
public class Main {
public static void main(String[] args)
throws Exception
{
// Get the instance for Locale US
NumberFormat nF
= NumberFormat
.getInstance(Locale.US);
// Prints the hash-code value
System.out.println("The hash-code values is: "
+ nF.hashCode());
}
}
输出:
The hash-code values is: 423132
