To understand this example, you should have the knowledge of the following Java programming topics:
Example 1: Generate Multiplication Table using for loop
public class MultiplicationTable {
public static void main(String[] args) {
int num = 5;
for(int i = 1; i <= 10; ++i)
{
System.out.printf("%d * %d = %d \n", num, i, num * i);
}
}
}
Output
5 * 1 = 5
5 * 2 = 10
5 * 3 = 15
5 * 4 = 20
5 * 5 = 25
5 * 6 = 30
5 * 7 = 35
5 * 8 = 40
5 * 9 = 45
5 * 10 = 50
The same multiplication table can also be generated using a while loop in Java.
Example 2: Generate Multiplication Table using while loop
public class MultiplicationTable {
public static void main(String[] args) {
int num = 9, i = 1;
while(i <= 10)
{
System.out.printf("%d * %d = %d \n", num, i, num * i);
i++;
}
}
}
Output
9 * 1 = 9
9 * 2 = 18
9 * 3 = 27
9 * 4 = 36
9 * 5 = 45
9 * 6 = 54
9 * 7 = 63
9 * 8 = 72
9 * 9 = 81
9 * 10 = 90
In the above program, unlike a for loop, we have to increment the value of i inside the body of the loop.
Though both programs are technically correct, it is better to use for loop in this case. It’s because the number of iteration (from 1 to 10) is known.
