Finally, have the programtake the LAST word and move it the the first word position. How do I do this with "scanner"? Hi! I'm learning the scanner in my java class.

Explanation / Answer

First we need to inport Scanner: importjava.util.Scanner; Now we can use it for input in main(): public staticvoid main(String[] args) { // create scanner toread input Scanner kb= newScanner(System.in); // prompt for userinput System.out.print("Enterthree words: "); // read threewords String word1= kb.next(); String word2= kb.next(); String word3= kb.next(); // combinewords String combined= word1+" "+word2+" "+word3; // convert to uppercase combined =combined.toUpperCase(); // output uppercase System.out.println(combined); // convert to lowercase combined =combined.toLowerCase(); // output lowercase System.out.println(combined); // put 3rd word in frontof first combined =word3+""+word1+" "+word2; // convert to lower caseagain (because we used the original input) combined =combined.toLowerCase(); // output System.out.println(combined); } Note: the above code reads each word separately,which makes dealing with them more clear.
