利用套件 java.util 中的 Scanner 類別, 來做資料輸入.

import java.util.Scanner;
public class Ch43
{
public static void main(String args[])
{
Scanner s=new Scanner(System.in);
String str1, str2;
int a;
float b;
System.out.print("請輸入一字串(帶空白): ");
str1=s.nextLine();
System.out.println(str1);
System.out.print("請輸入一字串(不帶空白): ");
str2=s.next();
System.out.println(str2);
System.out.print("請輸入一整數: ");
a=s.nextInt();
System.out.println(a);
System.out.print("請輸入一浮點數: ");
b=s.nextFloat();
System.out.println(b);
}
}
