Programming

Java

Write a program that will only accept input from a file providedas the first command line argument. If no file is given or the filecannot be opened, simply print “Error opening file!” and stopexecuting.

A valid input file should contain two lines. The first line isany valid string, and the second line should contain a singleinteger.

The program should then print the single character from thestring provided as the first line of input which is at the indexgiven in the second line.

If this cannot be done for any reason, the program should simplyprint “Error reading input!” and stop executing.

Complete your solution to this example in Exercise.java, whichis open to the left. You may use any combination of If-Thenstatements and Try-Catch statements to either prevent exceptionsfrom occurring or catching them when they do occur. Either approachis valid.
