java中的nextLine

package scanner;

import java.util.Scanner;

public class NextLine {
public static void main(String[] args) {
//nextLine()方法返回的是enter键之前的字符

Scanner line = new Scanner(System.in);

//想用两次就直接掉用两次，把nextLine赋值给字符串

String lineStr = line.nextLine();    //hello

String lines = line.nextLine();        //world

System.out.println("lineStr: " + lineStr);  //lineStr: hello

System.out.println("lines: " + lines);        //lines: world
}
}
