Question
Hello,
Please help write program in JAVA that prints out the Multiplication Table for a range of numbers (positive integers).
PROGRAM MUST DO THE FOLLOWING:
1) Prompt the user for a starting number: 'x'
2) Prompt the user for an ending number: 'y'
3) Print out the multiplication table of 'x' up to the number 'y'
SPECIFIC REQUIREMENTS
1) You must use the following method to load the array: public static void loadArray(int table[ ][ ], int x, int y)
2) You must use the following method to display the array: public static void printMultiplicationTable(int table[ ][ ], int x, int y)
3) You must load the table array with products of the factors. For example:
In Figure 1 below, the 5 x 5 array is loaded with the products for the times tables from 5 to 8
In Figure 2 below, the 2 x 2 array is loaded with the products for the times tables from 5 to 6

import java.util.*;
public class HelloWorld{
static int[][] table;
public static void loadArray(int table[][],int x,int y){
int temp;
int initial=x;
temp=x;
for (int row = 0; row < table.length ; row++)
{
for (int column = 0; column < table[row].length; column++)
{
table[row][column] = x*temp;
temp++;
}
x++;
temp=initial;
}
}
public static void printMultiplicationTable(int table[][],int x,int y){
for (int row = 0; row < table.length ; row++)
{
System.out.println();
for (int column = 0; column < table[row].length; column++)
{
System.out.printf("%2d ",table[row][column]);
}
}
}
public static void main(String []args){
int x,y,z;
Scanner cin=new Scanner(System.in);
System.out.println("Enter the first number x");
x=cin.nextInt();
System.out.println("Enter the first number y");
y=cin.nextInt();
if (x>y)
z=x-y+1;
else
z=y-x+1;
table = new int[z][z];
loadArray(table,x,y);
printMultiplicationTable(table,x,y);
}
}
Output:

Enter the first number y
