语法:
java public static final NumberFormat getIntegerInstance()参数:该功能不接受任何参数。
返回值:该函数返回整型值通用格式的 NumberFormat 实例。
下面是上述功能的实现:
程序 1:
```java // 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();
// Sets the currency to Canadian Dollar nF.setCurrency(Currency.getInstance(Locale.CANADA));
// Stores the values String values = nF.getCurrency().getDisplayName();
// Prints the currency System.out.println(values); } } ```
Output:
```java Canadian Dollar
```
程序 2:
```java // 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 values String values = nF.getCurrency() .getDisplayName();
// Prints the currency System.out.println(values); } } ```
Output:
```java US Dollar
```
