Someone please help me write this Java programs
i) Imagine you need to open a standard combination dial lock but don't know the combination and don't have a pair of bolt cutters. Write a Java program that prints all possible combinations so you can print them on a piece of paper and check off each one as you try it. Assume the numbers on the dial range from zero to thirty-six and three numbers in sequence are needed to open the lock. (5
ii) Suppose the lock isn't a very good one and any number that's no more than two away from the correct number in each digit will also work. In other words if the combination is 17-6-32, then 18-5-31, 19-4-32, 15-8-33 and many other combinations will also open the lock. Write a Java program that prints out a minimal list of combinations you would need to try to guarantee opening the lock.
Thanks alot.

Hi Friend,
Try the following code:
1)
class DialLock {
public static void main(String[] args) {
for( int i = 0; i <= 36; i++ )
{
for( int j = 0; j <= 36; j++ )
{
for( int k = 0; k <= 36; k++ )
{
System.out.println(i + "-" + j + "-" + k);
}
}
}
}
}
2)
class Combinationlock {
public static void main(String[] args) {
int i;
int j;
int k;
i = 2;
while (i <= 36) {
j = 2;
while (j <= 36) {
k = 2;
while (k <= 36) {
System.out.println(i + "-" + j + "-" + k);
k = k + 3;
}
j = j + 3;
}
i = i + 3;
}
}
}
Thanks
