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 * 优势一: 能够获取键盘输入的字符串 * 优势二: 有现成的获取int,float等类型数据，很是强大，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();  //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!");
