java程序用字符串初始化二维字符数组然后打印它

Question

enter code here WAP using multidimensional array to give the output as:

Mr. Smith
Ms. Jones

what i have tried is :

public class StringArray {
    public static void main(String args[])
    {
        int x=2,y=10,i,j;
        String[][] myStringArray = new String[x][y];

        myStringArray[0][y]="Mr.Bisht";
        myStringArray[1][y]="Mr.Kuthrpalli";

        for(i=0;i<2;i++)
        {
            for(j=0;j<10;j++)
            {
                System.out.println(myStringArray[i][j]);
            }
        }
    }
}

output: Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 10 at StringArray.main(StringArray.java:12)

public class StringArray{
public static void main(String args[])
{
  int x=2,y=10,i,j;
  String[][] myStringArray = new String[x][y];

  myStringArray[0][y-1]="Mr.Bisht";
  myStringArray[1][y-1]="Mr.Kuthrpalli";

  for(i=0;i<2;i++)
  {
    for(j=0;j<10;j++)
    {
        System.out.println(myStringArray[i][j]);
    }
  }
}

}

output:

Answer 1

myStringArray[0][y]="Mr.Bisht"; 

is executed with a value of y of 10 that is out of boundary.

Maximum value should be 9 because arrays are 0 based, so the range is from 0 to 9
