(1)把一个英语句子中的单词次序颠倒后输出。例如输入“how are you”,输出“you are how”;

(2)编写单元测试进行测试;

 

 

(3)用ElcEmma查看代码覆盖率,要求覆盖率达到100%。

 

 

package cyq;

 

import java.util.Scanner;

import org.junit.After;

public class Transpose {

/**

 * @param args

 */

 

 

public static void transpose(String str) {

 

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("颠倒顺序后的字符串:: " + result.toString());

 

}

 

}
