“java”怎样将一行数字之间带有空格逐个读取到控制台？

Answer 1

import java.util.Scanner;

public class laji1 {

public static void main(String[] args) {

int n;

Scanner scanner = new Scanner(System.in); 

System.out.print("请输入: ");

String yy = scanner.nextLine();

n=yy.length();

final char chr[]= new char[n]; 

yy.getChars(0, n,chr, 0); 

System.out.print("转变后的后缀表达式是:");

for(int i=0;i<n;i++){ 

System.out.print(chr[i]+" ");

}

}

}
