String[] names=new String[4];
int[] scores=new int[4];
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter 4 strings and integers:");
for(int i=0;i<4;i++){
names[i]=keyboard.nextLine();
scores[i]= keyboard.nextInt();
}
以上是我的簡單程序,下面顯示了彈出的異常。爲什麼在這個初級Java程序中得到InputMismatchException?
Enter 4 strings and integers:
first
1
second
Exception in thread "main" java.util.InputMismatchException

你可以提出任何方便的方法來拋棄'readInt'後的當前行嗎? – 2012-07-11 20:42:22
提示:事實上,當你閱讀第二個「名字」時,你已經在這麼做:) – Mat 2012-07-11 20:44:07
明白了。非常感謝你! – 2012-07-11 20:45:33
