java中的输入输出方法

输入

import java.util.Scanner;   

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

  /**  
   * Scanner类中的方法  
   * 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);   
  }   
}  

输出

System.out.println("hell,world!");
