Java - How do I make a String array with values?

I know how to make an empty array, but how do I make a String array with values from the start?

You could do something like this

String[] myStrings = { "One", "Two", "Three" };

or in expression

functionCall(new String[] { "One", "Two", "Three" });

or

String myStrings[];
myStrings = new String[] { "One", "Two", "Three" };

By using the array initializer list syntax, ie:

String myArray[] = { "one", "two", "three" };

Another way to create an array with String apart from

String[] strings =  { "abc", "def", "hij", "xyz" };

is to use split. I find this more readable if there are lots of Strings.

String[] strings =  "abc,def,hij,xyz".split(",");

or the following is good if you are parsing lines of strings from another source.

String[] strings =  ("abc\n" +
                     "def\n" +
                     "hij\n" +
                     "xyz").split("\n");

Another way is with Arrays.setAll, or Arrays.fill:

String[] v = new String[1000];
Arrays.setAll(v, i -> Integer.toString(i * 30));
//v => ["0", "30", "60", "90"... ]

Arrays.fill(v, "initial value");
//v => ["initial value", "initial value"... ]

This is more usefull for initializing (possibly large) arrays where you can compute each element from its index.

You want to initialize an array. (For more info - Tutorial)

int []ar={11,22,33};

String []stringAr={"One","Two","Three"};

From the JLS

The [] may appear as part of the type at the beginning of the declaration, or as part of the declarator for a particular variable, or both, as in this example:

byte[] rowvector, colvector, matrix[];

This declaration is equivalent to:

byte rowvector[], colvector[], matrix[][];
