public static void main(String[] args) {
getRandomPrints({"a" , "b" ,"c" , "d"});
}
public static void getRandomPrints(String[] args){
System.out.printLn("Hello World" + arg")
}
我在调用此方法时遇到问题,我想知道我在这里做错了什么。 它说
The method getRandomPrints(String[]) in the type test is not applicable for the arguments()
我想知道这里有什么不对,谢谢

试试这种方式
public static void main(String[] args) {
getRandomPrints(new String[]{"a" , "b" ,"c" , "d"});
}
public static void getRandomPrints(String[] args){
System.out.println("Hello World" + args);
}
我修复的编译时错误也很少,如println

您没有将正确的参数传递给方法:
getRandomPrints({"a" , "b" ,"c" , "d"});// not a valid array
这里也有一些更正:
System.out.printLn("Hello World" + args);
`l` ^ note `s` ^ ^ semicolon was missing
您可以试试这个:
public static void main(String[] args) {
getRandomPrints(new String[]{"a" , "b" ,"c" , "d"});//creating new array of string
}
public static void getRandomPrints(String[] args){
for(String s : args)
System.out.println(s);
}
或varargs
:
public static void main(String[] args) {
getRandomPrints("a" , "b" ,"c" , "d");
}
public static void getRandomPrints(String... args){//varargs to handle csv as array
for(String s : args)
System.out.println(s);
}
或split()
:
public static void main(String[] args) {
getRandomPrints("a,b,c,d".split(","));
}
public static void getRandomPrints(String[] args){
for(String s : args)
System.out.println(s);
}
