对于Formatter,请导入以下包-
import java.util.Formatter;
现在创建一个Formatter对象-
Formatter f1 = new Formatter();
现在,我们将使用Formatter格式化输出-
f1.format("Rank and Percentage of %s = %d %f", "John", 2, 98.5);
以下是一个例子-
import java.util.Formatter; public class Demo { public static void main(String args[]) { Formatter f1 = new Formatter(); Formatter f2 = new Formatter(); f1.format("Rank and Percentage of %s = %d %f", "John", 2, 98.5); System.out.println(f1.toString()); f2.format("Rank and Percentage of %s %s = %d %f", "David", "Warner", 1, 80.8); System.out.println(f2.toString()); } }
输出结果
Rank and Percentage of John = 2 98.500000 Rank and Percentage of David Warner = 1 80.800000
