[Java] Create an array to store 4 boolean values entered in by the user. Print out YES if all the values are true and NO if at least one value is false. 1. Using user input, collect four strings (either "true" or "false") from user

2. Keep prompting user for input if the string doesn’t equal "true" or "false"

3. Convert strings into boolean values

4. Store boolean values in an array

5. Print out the word YES if all array values are true; print NO if at least one array value is false

Write a new lc-3 trap subroutine (i.e. a subroutine that will be invoked via the trap instruction) that will receive a numeric digit entered at the keyboard (i.e. an ascii character), echo it to the screen, and return in r0 the corresponding numeric value: so if the user types the digit '7', the character '7' will appear on the screen, but the value returned in r0 will be b0000 0000 0000 0111 (#7) you may not use any trap calls in your code - you must implement the "polling" code that interrogates the keyboard status and data registers. ; getnum_tsr ; a subroutine for obtaining a numeric value ; given ascii numeric digit input to keyboard. ; the numeric digit is echoed to the console (e.g. '7' = b0000 0000 0011 0111), ; but the value returned in r0 is the actual numeric value ; corresponding to the digit (e.g. b0000 0000 0000 0111 =
