JAVA

Q1: Write the statements to create a 3 by 4 two-dimensional array of integers names x.

Q2: Provide the statements that would sequentially display the elements of the array x to the screen using System.out.println.

Q3: Provide the copy constructor for the following class:

public class X{

int r, c

public X(int r, int c) {

this.r = r;

this.c = c;

}

}

Q4: Write a piece of code that would create a 2 by 3 two-dimensional array, namedxArray, of objects of class X. The instance variables r and c of each element of the array should be initialized with the corresponding row and column of the object. For example, the object at row 1 column 2 should have an r of 1 and cof 2.

Q5: Provide a memory diagram of the array xArray and its content. Make sure to show all reference variables and index values.

You can draw your memory diagram on a piece of paper and scan or take a picture of your hand drawing
