A stem and leaf plot of the dataset is the representation of the distribution of the dataset without doing any calculation, in a stem and leaf plot the values of the dataset is spliited in two parts. Usually the last digit of the values is denoted as stem and next too it as leaf. It is arranged in ascending order.
The correct stem and leaf plot of the given dataset is plotted as:
| stem | leaf |
| 3 | 3 |
| 3 | none |
| 4 | none |
| 4 | none |
| 5 | 1 4 4 |
| 5 | 8 |
| 6 | 2 2 2 |
| 6 | none |
| 7 | 0 1 2 4 4 4 |
| 7 | 5 6 7 8 9 9 |
| 8 | 0 1 1 2 4 |
| 8 | none |
| 9 | 0 0 1 2 3 |

I need it in JAVA Write a program that randomly populates an array of size 100, sorts it, and then finds the median. The random numbers must be from 0-99 and all integer values. Also since there is an even set of numbers the median is found by taking the mean of the two middle numbers (In other words the 50th and 51st). You have to code your own sorting method. You may not use a built in java sorter....
