Please do this in java. This is a java program.

(1) Develop a computer program that generates random variate following Exponential distribution. The Mean of the distribution should be an input from the user at run-time. (2) Run your program from (1) to generate 1000 random variate with the input Mean=5. Plot a histogram. (3) Develop a computer program that generates random variate following Geometric distribution. The parameter (p = Probability(y 0)) should be an input from the user at run-time. (4) Run your program from (3) to generate 1000 random variate with the input p = 0.3 and plot a histogram.
