Write a program to generate all combinations of 1, 2 and 3 using for loop.
Here’s a Java program that generates all combinations of the numbers 1, 2, and 3 using nested for loops:
public class Combinations {
public static void main(String[] args) {
System.out.println("All combinations of 1, 2, and 3:");
for (int i = 1; i <= 3; i++) {
for (int j = 1; j <= 3; j++) {
for (int k = 1; k <= 3; k++) {
System.out.println(i + " " + j + " " + k);
}
}
}
}
}
Explanation:
- The program uses three nested
forloops. - The outer loop (
i) runs from 1 to 3. - The middle loop (
j) also runs from 1 to 3. - The inner loop (
k) runs from 1 to 3. - Inside the innermost loop, it prints the current values of
i,j, andk.
Output:
When you run this program, it will generate the following output:
All combinations of 1, 2, and 3:
1 1 1
1 1 2
1 1 3
1 2 1
1 2 2
1 2 3
1 3 1
1 3 2
1 3 3
2 1 1
2 1 2
2 1 3
2 2 1
2 2 2
2 2 3
2 3 1
2 3 2
2 3 3
3 1 1
3 1 2
3 1 3
3 2 1
3 2 2
3 2 3
3 3 1
3 3 2
3 3 3
