参数 :该函数不接受任何参数。

返回值 :该函数返回用于该数字格式的舍入模式。

下面是上述函数的实现。

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 instance for Locale US        NumberFormat nF            = NumberFormat.getInstance(                Locale.US);          // Prints the Rounding Mode        System.out.println("The rounding mode"                           + " value is: "                           + nF.getRoundingMode());    }}

输出。

The rounding mode value is: HALF_EVEN

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 instance for Locale CANADA        NumberFormat nF            = NumberFormat.getInstance(                Locale.CANADA);          // Prints the Rounding Mode        System.out.println("The rounding mode"                           + " value is: "                           + nF.getRoundingMode());    }}

输出。

The rounding mode value is: HALF_EVEN
