Initialization of Arrays of Strings: Arrays can be initialized after the declaration. It is not necessary to declare and initialize at the same time using the new keyword.

A more convenient way to initialize a C string is to initialize it through character array: char char_array[] = "Look Here"; This is same as initializing it as follows: char char_array[] = { 'L', 'o', 'o', 'k', ' ', 'H', 'e', 'r', 'e', '\0' };
Check if a String is contained in an Array using indexOf # We used the Array. indexOf method to check if the string two is contained in the array. If the string is not contained in the array, the indexOf method returns -1 , otherwise it returns the index of the first occurrence of the string in the array.
There are various ways in which you can declare an array in Java: float floatArray[]; // Initialize later int[] integerArray = new int[10]; String[] array = new String[] {"a", "b"};
You have several options:
string[] items = { "Item1", "Item2", "Item3", "Item4" }; string[] items = new string[] { "Item1", "Item2", "Item3", "Item4" }; string[] items = new string[10]; items[0] = "Item1"; items[1] = "Item2"; // ...
