programming in Java! what should I write next???

You have been asked to consider a random variable X that has 4 possible outcomes. Those outcomes areX = {1, 2, 3, 4}

1. Add code that prompts the user for the probability associated with each of the 4 outcomes (e.g. P (X =x)) and reads the values into the variables provided.

2. Determine whether each individual probability given by the user in (a) is valid. For each invalid P (x), print P(x) must be between 0 and 1 on a newline.

3. Determine if the 4 values entered collectively satisfy the requirements of a probability distribution. If they do not, print The sum of the individual outcome probabilities must sum to 1 on a newline.
