 # FCFS-scheduling-algorithm
 simulating FCFS algorithm in java 
+
+
+This small program simulating the FCFS scheduling algorithm .
+Simulating means waiting all process to finish as real life .
+That means will not give you the output immediately .
+
+The process created in .txt file as following :
+Pid AT Bt1 IO1 BT2 IO2 .... and so on
+
+The program will give :
+Pid At TotalBurstTime ComplitionTime TurnAroundTime WaitingTime 
+then gives the avarage of waiting time .
+
+The test cases design to success if the avg time is in 
+correct range because there is no one exact solution in multithreading
+DO NOT run more than test case in same time .
+
