String [] tempString = multipleValues.split（“-”）; 但是int用于创建数组的格式String [] array = new String [10] ;?

Question

public void pushMany(String multipleValues){
String[]tempString=multipleValues.split("-");
for(int i=0;i<tempString.length;i++){
    push(tempString [i]);   
    }
}

I am used to creating arrays using String[]array=new String[10]; or creating multidimensional arrays such as String[]array={"car","truck"}; Therefore, I am not sure what is going on with this??? Is it still assigned an array?

Answer 1

String.split("-") function returns an array of Strings separated by "-". Therefore yes it is assigned an array!

Refer to this link for more information.

Answer 2

The Javadoc is quite clear:

[Returns] the array of strings computed by splitting this string around matches of the given regular expression

so yes, the value assigned to tempString is a String[] .

Answer 3

The String class has a method split

public String[] split(String regex)

Quoting the java doc :

Splits this string around matches of the given regular expression.

This method works as if by invoking the two-argument split method with the given expression and a limit argument of zero.

Trailing empty strings are therefore not included in the resulting array.

so when you do split("-") you are searching conincidences in the string that matches the "-" and the result is an array
