I have an array of strings. How can I convert it to System.Collections.ArrayList?

So how to convert String array to String in java. We can use Arrays. toString method that invoke the toString() method on individual elements and use StringBuilder to create String. We can also create our own method to convert String array to String if we have some specific format requirements.
1) First split the string using String split() method and assign the substrings into an array of strings. We can split the string based on any character, expression etc. 2) Create an ArrayList and copy the element of string array to newly created ArrayList using Arrays. asList() method.
String[] and String... are the same thing internally, i. e., an array of Strings. The difference is that when you use a varargs parameter ( String... ) you can call the method like: public void myMethod( String... foo ) { // do something // foo is an array (String[]) internally System.
string[] myStringArray = new string[2];
myStringArray[0] = "G";
myStringArray[1] = "L";
ArrayList myArrayList = new ArrayList();
myArrayList.AddRange(myStringArray);
