Software Test second Job

(1) Write a program that parses the frequency of occurrences of each word in a string and displays the word and the frequency at which it appears. (the words are separated by a space, such as "Hello World My First Unit Test");

(2) Writing unit tests for testing;

(3) Use Elcemma to view code coverage, requiring coverage to reach 100%.

1) Import java.util.ArrayList;

Import java.util.Collections;

Import Java.util.Comparator;

Import Java.util.HashMap;

Import java.util.List;

Import Java.util.Map;

Import Java.util.Map.Entry;

public class Mapsort {

public static void Main (string[] args) {

String str = "Hello World My first Hello Unit Test";

string[] items = Str.split ("");

map<string, integer> map = new hashmap<string, integer> ();

for (String S:items) {

if (Map.containskey (s))

Map.put (S, map.get (s) + 1);

else {

Map.put (S, 1);

}

}

list<entry<string, integer>> list = new arraylist<entry<string, integer>> ();

For (entry<string, integer> entry:map.entrySet ()) {

List.add (entry);

}

Collections.sort (list, new Entrycomparator ());

For (entry<string, integer> obj:list) {

System.out.println (Obj.getkey () + "\ T" + obj.getvalue ());

}

}

}

Class Entrycomparator implements Comparator<entry<string, integer>> {

public int Compare (entry<string, integer> O1, entry<string, integer> O2) {

return O1.getvalue () > O2.getvalue ()? 0:1;

}

}

1. use of the Learning Unit Test Code Coverage tool

(1) The order of words in an English sentence is reversed and then output. For example, enter "How IS is", output "you is how";

(2) Writing unit tests for testing;

(3) Use Elcemma to view code coverage, requiring coverage to reach 100%.

1) package junit4.demo;

import Java.util.Scanner;

Public class Reversal {

Public Static void Main (string[] args) {

Scanner input = new Scanner (System. in);

System. out. Print ("Please enter English:");

String str = input.nextline ();

string[] Strarr = Str.split ("\\s+|[,]");

StringBuffer result = new stringbuffer ();

for (int i = strarr.length-1;i >=0; i--) {

Result.append (Strarr[i] + "");

}

Result.setcharat (Str.length ()-0, (char) 0);

System. out. println ("Reversed order results are:" +result.tostring ());

}

}
