Question

java中，假如我要输入一个字符串，应该怎么写代码啊？

Answer 1

import java.util.*;
public class zifu {
public static void main(String[] args) {
int n=100;
Scanner scanner = new Scanner(System.in);
System.out.print("请输入字符串: ");
String yy = scanner.nextLine();
StringTokenizer fenxi1 = new StringTokenizer(yy," ");
String str[] = new String[n];
for(int i=0;fenxi1.hasMoreTokens();i++){
str[i]=fenxi1.nextToken();
}
for(int i=0;i<=n-1;i++){
if(str[i]!=null)
System.out.print(str[i]+" ");
}
}
}

是不是这个？

import java.util.Scanner;

public class F {
public static void main(String[] args){
Scanner sc=new Scanner(System.in);
System.out.print("请输入一个字符串：");
String str=sc.next();
System.out.println(str);
}
}

用scanner就可以了
import java.util.Scanner;

public class A{
public static void main(String args[]){
Scanner scanner = new Scanner(System.in);
String input = scanner.nextLine();
}
}
