(Display four patterns using loops) Ask the user to enter an integer to set a limit for nested loops and generate the following four patterns: Enter an integer to be a limit of the pattern:6 Pattern A: 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5 1 2 3 4 5 6 Pattern B: 1 2 3 4 5 6 1 2 3 4 5 1 2 3 4 1 2 3 1 2 1 Pattern C: 1 2 1 3 2 1 4 3 2 1 5 4 3 2 1 6 5 4 3 2 1 Pattern D: 1 2 3 4 5 6 1 2 3 4 5 1 2 3 4 1 2 3 1 2 1 Complete answer in java please. this is what i have including error message:
