import java.util.Scanner;   

public class EnterTest {   

  public static void main(String[] args) { //主方法
    ScannerTest();//调用ScannerTest方法
  }   

  /**

   * 优点一: 可以获取键盘输入的字符串
   * 优点二: 有现成的获取int,float等类型数据，非常强大，也非常方便；
   */
  public static void ScannerTest(){
    Scanner sc = new Scanner(System.in);
    System.out.println("ScannerTest, Please Enter Name:");
    String name = sc.nextLine();  //读取字符串型输入
    System.out.println("ScannerTest, Please Enter Age:");
    int age = sc.nextInt();    //读取整型输入
    System.out.println("ScannerTest, Please Enter Salary:");
    float salary = sc.nextFloat(); //读取float型输入
    System.out.println("Your Information is as below:");
    System.out.println("Name:" + name +"\n" + "Age:"+age + "\n"+"Salary:"+salary);
  }
}
