利用 printf() 函式, 規範輸出字串的格式.
public class ch63
{
public static void main(String args[])
{
String a="There are %d cats and %d dogs.%n"; // %d 輸出整數 %n 換行
String b="There are %f cats and %.2f dogs.%n"; //%f 輸出浮點數 .2 四捨五入至小數後第二位
String c="There are %s cats, %d dogs, %s pigs, and %d rabbits.%n"; //%s 字串
System.out.printf(a,5,7);
System.out.printf(b,5.0,7.0);
System.out.printf(c,"5",7,"2",3);
}
}
