Program 3
The program displays multiplication table using nested while loop.
class nestedwhileloop
{
public static void main (String args[])
{
int i=1, j=1;
System.out.println(“Tables”);
while(i<=2)
{
while(j<=12)
{
System.out.println(i+”*”+j+”=”+(i*j));
j++;
}
i++;
System.out.println(“”);
j=1;
}
}
}
When you execute above code , it produces the folloing result.
