我可以将字符串输入中的字符分开,但我的问题是:
Enter an integer: 123
输出是:
Individual digits: 1 Individual digits: 2 Individual digits: 3
它还复制了“个人数字”,这不是意图..这是我的代码
public class gradedExer1A {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner sc = new Scanner(System.in);
System.out.print("Enter an integer: ");
String input = sc.nextLine();
int len = input.length();
for(int i = 0; i < len ; i++) {
char in = input.charAt(i);
System.out.print("Individual digits: " + in + " ");
}
}
}
答案 0 :(得分:1)
尝试
System.out.print("Individual digits: ");
for(int i = 0; i < len ; i++) {
char in = input.charAt(i);
System.out.print(in + " ");
}
