    Default Can anyone help with this question

    The following exercises are based on those from the lecture notes. Please refer to the lecture notes for any
    information required and then carry out the following exercises plus any additional tasks as described. You will need
    to create Java classes based on those in the lecture notes, or create your own, as appropriate.
    1. Create a file arrayslist, and place the Java code that solves each of the following problems within it.
    (a) Write a Java program that declares and initialises three arrays A, B and C all of length five. A and B are of
    type int and C is of type String.
    (b) Create an int array called D of length five.
    (c) Populate the array of Strings C (question 1) with words of your choice, use a for loop to print out every
    element of the array C.
    (d) Modify your for loop code so that it loops through every element in the array C and at the end tells you
    which of the words in C has the longest length.

    I have done this bit
    //one way (notice the int and intArray2[])
    int intArray[] = new int[3];
    intArray[2] = 1;

    //another way (notice the difference with int[] and intArray2)
    int[] intArray2 = new int[3];
    intArray2[2] = 1;

    //array of strings
    String[] strArray = new String[5];
    strArray[2] = "hello";

    //prints hello
    System.out.println(strArray[2]);

    [code]
    **YOUR CODE GOES HERE**
    [/code]
