菜鸟提问:简单的JAVA控制台输入的问题 输入多个测试实例。。
Java code

public static void main(String[] args){
    Scanner sc=new Scanner(System.in);
    String [][] a=new String [2][];
    String [] b=null;
    for(int i=0;i<a.length;i++)
    {
        b=sc.nextLine().split(" ");
        for(int j=0;j<b.length;j++)
        {
            a[i]=b;
        }
}
    for(int i=0;i<a.length;i++){
        for(int j=0;j<b.length;j++){
            System.out.print(a[i][j]+" ");
        }
        System.out.println();
    }
    }
    


输入格式为:
i like china
i want to stay in there
错误为:
i like china Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 3
at exam2.main(exam2.java:17)
输入格式为:
i want to stay in there
i like china
输出为:
i want to
i like china
怎么解决呢????


------解决方案--------------------
Java code

for(int i=0;i<a.length;i++){
        for(int j=0;j<b.length;j++){
            System.out.print(a[i][j]+" ");
        }
        System.out.println();
    }

 //改为
for (int i = 0; i < a.length; i++) {
            for (int j = 0; j < a[i].length; j++) {
                System.out.print(a[i][j] + " ");
            }
            System.out.println();
        }
