Please keep it simple,
Use only the notes above, do the following :
1. Complete the method numWords() that accepts a string and returns the number of words in the string.
2. Complete the method getLastWord() that accepts a string and returns the last word in the string.
3. Complete the method alternateCase() that accepts a String and returns a new String with alternating case. For example:
Input: ""String Programming in Java is fun"
Return value: "StRiNg pRoGrAmMiNg iN JaVa iS FuN"
4. Complete the method printIndices that accepts a String source and a character search, and prints the position of each occurrence of the search value in source. For example:
Input: source = "String Programming in Java is fun", search = 'i'
Console Output: 3 15 19 27
Here is the incomplete source code below:
/**

* @author

*/
public class StringsPairProgram {
/**
*
* @param sentence
* @return
*/
public static int numWords(String sentence) {
return 0 ;
}
/**
*
* @param sentence
* @return
*/
public static String getLastWord(String sentence) {
return "";
}
/**
*
* @param sentence
* @return
*/
public static String alternateCase(String sentence) {
return "";
}
public static void printIndices(String source, char search) {
}
/**
*
* @param args
*/
public static void main(String[] args) {
String sentence = "String Programming in Java is fun";
System.out.println("Expected numWords() returns 6 : " + numWords(sentence));
System.out.println("Expected getLastWord() returns fun : " + getLastWord(sentence));
System.out.println(
"Expected alternateCase() returns StRiNg pRoGrAmMiNg iN JaVa iS FuN : " + alternateCase(sentence));
System.out.println("Expected printIndices() prints indices 3 15 19 27 for search letter i : ");
printIndices(sentence, 'i');
}
}
