You are asked to write a java program for a university. The university saves student's information in a text file. However, there are some constraints: i) the student age should be within 18 to 25, ii) the student HSC GPA should be over 4.5. Write down exceptions and handle the exception if a user inputs incorrect student information.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
