先看解释: nextInt(): it only reads the int value, nextInt() places the cursor in the same line after reading the input. next(): read the input only till the space. It can't read two words separated by space. Also, next() places the cursor in the same lin
原创 Java中Scanner类中的方法next()和nextLine()都是吸取输入台输入的字符,区别: next()不会吸取字符前/后的空格/Tab键,只吸取字符,开始吸取字符(字符前后不算)直到遇到空格/Tab键/回车截止吸取: nextLine()吸取字符前后的空格/Tab键,回车键截止. import java.util.Scanner; import java.util.Vector; public class Main{ public static void main(String
转 import java.util.ArrayList; import java.util.Scanner; public class Test { public static void main(String[] args) { ArrayList<Student> list = new ArrayList<Student>();//定义一个学生类 Scanner input = new Scanner(System.in);//创建一个扫描器对象,用于读取从控制台输入 int
通过一段代码就可以明白其中的奥妙!! import java.util.Scanner; public class next_nextLine { public static void main(String[] args) { Scanner s = new Scanner(System.in); System.out.println("输入第一个字符串:"); String s1 = s.nextLine(); System.out.println(s1); System.out.
