Help Please!!

Write Java statements to do the following: Declare an array named alpha of 5 rows and 10 columns of type char. Initialize each element of the array alpha, from step 1, to the character 'B'. Next write a code snippet using loops to store 'A' in first and last row of alpha, and the first and last column of alpha, all other cells should contain 'Z'. A A A A A A Z Z Z A A Z Z Z A A Z Z Z A A Z Z Z A A Z Z Z A A Z Z Z A A Z Z Z A A Z Z Z A A A A A A Consider the following declarations: What is stored in beta after each of the following statements executes:

Explanation / Answer



public class ArrayTest{

    public static void main(String[] args) {
        char[][] alpha = new char[5][10];
       
        //    Initializing with 'B'
        for(int i=0; i<5; i++ ) {
            for(int j=0;j<10;j++) {
                alpha[i][j] = 'B';
            }
        }
       
       
        for(int i=0; i<5; i++ ) {
            for(int j=0;j<10;j++) {
                if (i==0 || i==4) {
                    alpha[i][j] = 'A';
                }
                else if(j==0 || j==9) {
                    alpha[i][j] = 'A';
                }
                else {
                    alpha[i][j] = 'Z';
                }
               
            }
        }
        for(int i=0; i<5; i++ ) {
            for(int j=0;j<10;j++) {
                System.out.print(alpha[i][j] + " ");
            }
            System.out.println();
        }
       
    }

}


Output:


A A A A A A A A A A
A Z Z Z Z Z Z Z Z A
A Z Z Z Z Z Z Z Z A
A Z Z Z Z Z Z Z Z A
A A A A A A A A A A


b)

Output:
