2. Task (reuse of code at work!): Rewrite the previous program and make it work when the list is populated with values found in an input file. The name of the file should be input from the user. Handle all possible cases (use try/catch statements). Have a constant for max size and read at most these many values from the file. Your output should be similar to the following samples: SAMPLE OUTPUT # 1: neaso input the name of the file be opened: input.tx Fil Nat. Found! Exit program! SAMPLE OUTPUT #2: For this file holding all values of unwanted types: a nd fderfd sdfgvdfS23 tdaf, asdas? ergenwr Please input thename of the ile be opened: input.txt The file doesn'contain any integers. Exit program! __ SAMPLE OUTPUT #3: For this tile holaina mixed types: 34 a SS 18 47 89 b 4S 6? S9 ab0bb 88 32 20 23 10 78 39 21 nm gntt Please input the mame of the file so he opened: input2.txt The lis. size is: 16 34 S5 18 9 6 59 88 37 0 27 10 78 39 21 Your optians are: All even values?
