Do these steps on paper first and then enter into a text file to submit

1. Write a declaration for an array which can contain 5 integers.

2. Write a statement that puts the value 100 into the 3rd cell.

3. Write a statement that both declares an array of single characters and initializes the cells to these values: ‘a’, ‘b’, ‘c’.

4. Write a code segment that declares an array of 5 Strings, and then uses a loop to insert 5 String values into the array. Now you will start writing code. Create a project called Lab7 in Eclipse.

5. Create a class called StringListFun. In your main method, declare and initialize an array that holds String values, and initialize it with \"apple\", \"avocado\", \"eggplant\", \"carrot\", \"chard\", \"tomato\". Write a loop that prints out the contents of the array.

6. Add a loop that prints out the contents of the array in reverse.

7. Add a loop that prints out the values at even positions in the array.

8. Declare a second array of String named list2. Write a loop that copies the values in your array into list2. Then write another loop that prints out list2.

Solution

Hi, Please find my code.Please let me know in case of any issue:

1.
   int[] arr = new int[5];

2.
   arr[2] = 100; (array index start from 0)

3.
   char[] charArr = {\'a\', \'b\', \'c\'};
