Java Program

Write a program to analyze a log file to get the 50 percentile of the "E" values when the field "is_safe" equals to 1. The following are two example records from the log: batch O||is_safe:0,E=100;is_safe:1,E=101;&&batch 2||is_safe:0,E=100;is_safe:1,E=102;is_safe:1, E=12; - - The records are separated by && - Please infer other formatting rules from these two example records The first record is_safe equals to O so the record should be ignored in calculation. The second record has is_safe=1, so the E value 102 should be included in calculation. For this particular example, there are 3 E values with is_safe=1 (12,101,102), so the final output should be 101. If the number of observations is even, then the 50 percentile is the simple average of the middle two numbers. Please note: There might be malformed lines, you should discard the entire line if you detect any errors (for example extra spaces thats different from the example above)
