软件测试第二次作业1(1)(2)
(1)实现代码如下:
package cn.guo.mju;
public class Action {
public void findWord(String str){//划分单词
String[] arrayWord =str.split(" ");
Action a = new Action();
a.frequency(arrayWord);
}
public void frequency(String[] arrayWord){
String[] word = new String[arrayWord.length];//存放遍历过的单词
int time[]=new int[arrayWord.length];//存放记录单词出现次数
boolean t = true;
for(int i=0;i<arrayWord.length;i++){
for(int j=0;j<arrayWord.length;j++){//遍历已遍历过的单词表
if(arrayWord[i].equals(word[j])){
System.out.println("单词重复!!!");
t=false;//如果单词重复则跳过
}
}
if(t==true){//单词初始次数为1
word[i]=arrayWord[i];
time[i]=1;
for(int j=i+1;j<arrayWord.length;j++){//遍历字符串,记录次数
if(arrayWord[i].equals(arrayWord[j])){
time[i]++;
}
}
}
}
for(int i = 0;i<arrayWord.length;i++){//遍历输出次数
if(word[i]!=null){
System.out.println("单词:"+word[i]+"出现了"+time[i]+"次。");
}
}
}
}
package cn.guo.mju;
import java.util.Scanner;
public class View {
public View(){
Scanner input =new Scanner(System.in);
System.out.println("请输入字符串,单词用空格隔开,回车结束:");
String str=input.nextLine();
Action a = new Action();
a.findWord(str);
}
}
package cn.guo.mju;
public classMain {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
View v = new View();
}
}
结果如下:
(2)单元测试的实现代码如下:
package cn.guo.mju;
import org.junit.Before;
import cn.gmh.mju.test2;
public class ActionTest {
@Before
public void setUp() throws Exception {
}
public void test() throws Exception {
String str="Hello World My First Unit Test";
Action action=new Action();
action.findWord(str);
}
}
结果如下:
