我想确保这段代码返回一个字符串对象。字符串对象返回
class ShoutBox extends Clone{
public static String ShoutOutRandomMessage(){
//holds the words to be generated.
String[] subject= {" Jim is", " Henry is", " Carter is"};
String[] verb= {" eating", " catching", " studying", " caughing"};
String[] adjective= {" funny", " hard", " good", " polite"};
String[] object= {" course", " homework", " books", " dog"};
String[] adverb= {" quickly. ", " everywhere. ", " accordingly. ", " awfully. "};
Random r = new Random(); //intialize a Random
int selectedElement = r.nextInt(subject.length);
{
//This Method will grab a word from the above list.
String randomSentence = subject[selectedElement]
+ verb[selectedElement]
+ adjective[selectedElement]
+ object[selectedElement]
+ adverb[selectedElement];
System.out.println("Here is your Random Generated Sentence"+"\n");
System.out.println(randomSentence + "\n\n");
//This method will print the random sentence.
return String.format(randomSentence);
}
//Is this code returning a string object.
}
问题是什么? – sstan
如果它没有返回* a *字符串,它返回什么?无论如何,内部的'{}'是多余的,可以在不改变程序的情况下移除。 – user2864740
当你声明一个返回类型为String的方法时,这意味着它可以返回一个String对象的引用,或者它可以返回null,或者它可以抛出一个Exception或者一个'错误“,否则它可能无法终止。没有其他选择。在你的情况下,是的,这会返回一个'String'。 –
