Java中不兼容的返回类型

Question

I have the following method: (from this WSDL URL: http://services.aonaware.com/DictService/DictService.asmx?WSDL )

private static WordDefinition define(java.lang.String word) {
    com.aonaware.services.webservices.DictService service = new com.aonaware.services.webservices.DictService();
    com.aonaware.services.webservices.DictServiceSoap port = service.getDictServiceSoap();

    return port.define(word);
}

It takes a word from a jTextField and returns a list of its definitions.

I have declared the following list:

List<WordDefinition> def = new ArrayList<WordDefinition>();

I want to print the result I get from the method. So I made the following loop:

    for (int i=0; i< def.size(); i++){
        System.out.println(Arrays.deepToString(def));
    }

where:

    String str = jTextField1.getText();
    def = define(str);

The error is get is the following:

Incompatible types: List cannot be converted to Object[]

Any help would be greatly appreciated.

Answer 1

您需要将列表转换为Arrays.deepToString（）才能接受的数组： Arrays.deepToString(def.toArray())

Answer 2

I see a lot of confusion.

First of all, the static method define returns you a WordDefinition , not a List<WordDefinition> , so the line

def = define(str)

should give you a compile error.

Anyway, assuming List<WordDefinition> def is actually the variable you have with content, either you use Arrays.deepToString OR you iterate over the List, not both.

If you want to iterate, you can just do:

for(WordDefinition wd: def){
    System.out.println(wd);
}

or

Arrays.deepToString(def.toArray());
