Java NumberFormat getMinimumFractionDigits()方法及示例

getMinimumFractionDigits() 方法是 java.text.NumberFormat 的一个内置方法，用于返回一个实例的数字的分数部分所允许的最小数字。

语法:

public int getMinimumFractionDigits()

参数：该函数不接受任何参数。
返回值 ：该函数返回分数部分允许的最小数字。以下是上述函数的实现：

程序1 :

// 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 Integer instance
        NumberFormat nF
            = NumberFormat
                  .getIntegerInstance();
 
        // Stores the minimum
        int value
            = nF.getMinimumFractionDigits();
 
        // Prints the maximum fraction
        System.out.println("The minimum "
                           + "Fraction digits: "
                           + value);
    }
}

输出

The minimum Fraction digits: 0

程序2

// 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 Currency instance
        NumberFormat nF
            = NumberFormat
                  .getCurrencyInstance();
 
        // Stores the minimum
        int value
            = nF.getMinimumFractionDigits();
 
        // Prints the minimum
        System.out.println("The minimum "
                           + "Fraction digits: "
                           + value);
    }
}

输出
