How would I code the 100 point version so that it outputs the Expected output?

Student Version of StringMethods: public class StringMethods { /* * method getFirst() returns all letters before the delimiter in line */ public static String getFirst( String line, String delimiter ) { return ""; } /* * method getLast()returns all letters after the delimeter in line */ public static String getLast( String line, String delimiter ) { return ""; } /* * method removeComma() if there is a comma in parameter word, * returns word without the comma; else returns word */ public static String removeComma( String word ) { return ""; } /* * method getNumUpper() returns the number of uppercase letters in line. */ public static int getNumUpper( String line ) { return 0; } /* * method displayWords() displays the individual words, * one per line, in the parameter phrase */ public static void displayWords(String phrase) { } public static void main( String args[] ) { // test methods getFirst and getLast - 80 pt version System.out.println( getFirst("elephants@are@big", "@") ); System.out.println( getFirst("computer$science", "$") );

System.out.println( getFirst("dogs@are@not@smarter@than@cats", "@") ); System.out.println( getFirst("one#fish#blue#fish", "#") ); System.out.println( getLast("elephants@are@big", "@") ); System.out.println( getLast("computer$science", "$") ); System.out.println( getLast("dogs@are@not@smarter@than@cats", "@") ); System.out.println( getLast("one#fish#blue#fish", "#") ); System.out.println(" "); // test method getNumUpper - 90 pt version System.out.println(" Number of uppercase letters in: "); String line = "Computer Science"; System.out.println(line + " : " + getNumUpper(line)); line = "AP " + line; System.out.println(line + " : " + getNumUpper(line)); line = "The Cat in the Hat Comes Back by Dr. Suess"; System.out.println(line + " : " + getNumUpper(line)); // test remove comma - 100 pt version System.out.println(" Remove comma"); System.out.println( removeComma("Tweety,Bird")); System.out.println( removeComma("Sylvester")); System.out.println( removeComma(",YosemiteSam")); // display the words, one per line in the string - 110 pt version line = "I love unicorns"; System.out.printf(" \"%s\" contains the words: ", line ); displayWords(line); line = "Did I ever tell you that Mrs. McCave had twenty-three sons and she named them all Dave?"; System.out.printf(" \"%s\" contains the words: ", line ); displayWords(line); } }
