DecimalFormat类简单用法示例

import java.text.*;
public class hello {
	//自定义方法，根据参数传入的匹配模式，来格式化数字
	public static void cuntomFormat(String pattern,double value)
	{
		DecimalFormat myFormatter=new DecimalFormat(pattern);
		//创建模式对象
		String output=myFormatter.format(value);
		System.out.println(value+" "+pattern+" "+output);
		
	}
	public static void main(String[] args)
	{
		cuntomFormat("###,###.###",123456.789);
		cuntomFormat("###.##",123456.789);
		cuntomFormat("00.000",123.78);
		cuntomFormat("$###,###.###",12345.67);
		

		
	}

}
