将二维数组类型由整型改成字符串型，结果赋值时总是跳过第一个数从第二个开始赋值

import java.util.Scanner;

public class ArrayTest {//类名定义太随意！
    /**
     * @param args
     */
    public static void main(String[] args)
    {
        Scanner in=new Scanner(System.in);
        System.out.println("请输入二维数组的行数：");   
        int left=in.nextInt();
        System.out.println("请输入二维数组的列数：");   
        int right=in.nextInt();
        int i,j = 0;
        String [][] anArray=new String[left][right];
        System.out.println("请为此二维数组赋值：");   
        in=new Scanner(System.in);//加这句就好
        for(i=0;i<left;i++)
            for(j=0;j<right;j++)
                anArray[i][j]=in.nextLine();
        Shuzu(left,right,anArray);
    }
    public static void Shuzu(int left,int right,String anArray[][])
    {        
        System.out.println("二维数组输出：");   
        int i,j;
        int m,n;
        for(i=0;i<left;i++)
            for(j=0;j<right;j++)
            {
                m=i+1;
                n=j+1;
                System.out.println("第"+m+"行"+n+"列：");
                System.out.println(anArray[i][j]+" ");
            }
    }
}
