Help fixing my code

I need help fixing my code. You can find my code down below and the output it's suppose to produce. It's threads question where it should take input and the number of lines of the input should be calculated and it should be decided how many lines each thread should read. For example, if the input contains 10 lines and there are 5 threads, the threads must read 2 lines at a time. When this value is fractional, the value should be rounded up. For example, if a 14-line file is being read and the number of threads at hand is assumed to be 5, 3 lines will be read in each thread operation. And at the end Each thread will return its own sums after line reading and calculation, and print the total value to the screen. So, basically the output down below should be printed when given the input below.

sample input:

1.23 2.66 3.45 81.23 9.11 3.33 7.78 4.12 1.11 2.22

output:

Thread 1 reads 1. line. The value is 1.23 Thread 1 reads 2. line. The value is 2.66 Shared Resource: 3.89 Thread 2 reads 3. line. The value is 3.45 Thread 2 reads 4. line. The value is 81.23 Shared Resource: 88.57 Thread 3 reads 5. line. The value is 9.11 Thread 3 reads 6. line. The value is 3.33 Shared Resource: 101.01 Thread 4 reads 7. line. The value is 7.78 Thread 4 reads 8. line. The value is 4.12 Shared Resource: 112.91 Thread 5 reads 9. line. The value is 1.11 Thread 5 reads 10. line. The value is 2.22 Shared Resource: 116.24
