Number Patterns using loops in Java

Question

I have been trying different variations of for loops and have no clue how to make these patterns:

Pattern 1

54321
5432
543
54
5

Pattern

Answer 1

Since you posted an attempt for pattern one, I'll tell you a solution for pattern one -

int rows = 5; // <- Start at 5.
for (int i = rows; i > 0; i--) { // <- Use decrementing loop(s).
  for (int j = rows; j > rows - i; j--) { // <- Start at 5 (again)
    System.out.print(j);
  }
  System.out.println();
}

Output is pattern 1 in your question,

54321
5432
543
54
5
