import java.util.Scanner; public class EnterTest { public static void main(String[] args) { //主方法 
    ScannerTest();//調用ScannerTest方法 
 } /** * Scanner類中的方法 * 優勢一: 能夠獲取鍵盤輸入的字符串 * 優勢二: 有現成的獲取int,float等類型數據，很是強大，也很是方便； */  
  public static void ScannerTest(){ Scanner sc = new Scanner(System.in); System.out.println("ScannerTest, Please Enter Name:"); String name = sc.nextLine();  //讀取字符串型輸入 
    System.out.println("ScannerTest, Please Enter Age:"); int age = sc.nextInt();    //讀取整型輸入 
    System.out.println("ScannerTest, Please Enter Salary:"); float salary = sc.nextFloat(); //讀取float型輸入 
    System.out.println("Your Information is as below:"); System.out.println("Name:" + name +"\n" + "Age:"+age + "\n"+"Salary:"+salary); } }
