java - java中无法接受字符输入

Question

我是java新手，我想接受如下输入:

0 2 a

我能够接受整数输入，但无法接受字符输入。

我正在使用以下代码

Scanner s = new Scanner(System.in);
int o = s.nextInt();
    if(o==0)
        {
             int l=s.nextInt();
             char c=s.next().charAt(0);
        }

Answer 1

May be Thats because the Scanner#nextInt method does not read the last newline character of your input, and thus that newline is consumed in the next call to Scanner#nextLine.

在 nextInt 之后触发一个新行。

    Scanner s = new Scanner(System.in);
    int o = s.nextInt();
    s.nextLine();
        if(o==0)
            {
                 int l=s.nextInt();
s.nextLine();
                 char c=s.next().charAt(0);
            }
