標題: printf() 輸出練習 [打印本頁]

作者: tonyh 時間: 2019-7-5 13:57 標題: printf() 輸出練習

試以 printf() 方法做字串輸出。
%d 整數
%s 字串
%S 轉換為大寫字母的字串
%.2f 四捨五入至小數點後2位

public class Ch60
{
public static void main(String[] args)
{
String str1="dog", str2="cat";
int a=3, b=5;
double total=21.3568;
System.out.printf("There are %d %ss and %d %Ss totally weigh %.2f pounds.",a,str1,b,str2,total);
}
}
