Exceptions that are common in arrays

The common exceptions in the array are: 1, array subscript out of bounds exception 2, array null pointer exception, and NULL pointer exception is divided into 3 kinds, the code example is as follows:

public class Exception1 {
    public static void Main (string[] args) {
        1, array subscript subscript out of bounds exception: Java.lang.ArrayIndexOutOfBoundsException
        int[] I=new int[10];
        i[10] = 8;//subscript out of bounds
        System.out.println (i[10]);

        2. Null pointer exception java.lang.NullPointerException
        First Kind
        boolean[] B=new boolean[3];
        b=null;//null pointer exception appears here
        System.out.println (b[0]);

        The second Kind
        string[] Str=new string[5];
        str[4]=new String ("AA");//or write str[3]= "AA" without writing this sentence will appear null pointer exception
        System.out.println (str[4].tostring ());

        Third Kind
        Int[][] J=new int[3][];
        j[1][0]=6;//first address is NULL, unable to find the specified value
    }

}
