in java on intellij please , just need some help as i am confused by the question

Modify the program so that rather than printing out the two strings which have been read in, it Keats them as being two halves of a single integer. Your program should print out the value of that integer plus 1. For example, after the following code has been executed the value of k will be the integer 44. String s="45 int k= Integer.parseInt(s) 1 Here is how your modified program should behave (user input is shown highlighted): Enter a line: 23 Enter another line: 99 Number =2400 The complete number is 2399 and adding 1 gives 2400
