![]() Use Matcher.quoteReplacement() to suppress the special meaning of these characters, if desired. If the method takes two arguments, then a String representation of the first argument in the radix specified by the second. If the method takes a primitive data type as an argument, then the String object representing the primitive data type value is returned. Thus, after the declaration, we proceed to initialize the array.Ī String array can be initialized either inline along with the declaration or it can be initialized after declaring it.įirst, let’s see how a String array can be initialized inline. Note that backslashes (\) and dollar signs () in the replacement string may cause the results to be different than if it were being treated as a literal replacement string see Matcher.replaceFirst(). The method is used to get a String object representing the value of the Number Object. Otherwise, the default values that are assigned to String elements are null. Once the String Array is declared, you should initialize it with some values. ![]() So when individual elements of this String array are printed, the values of all the elements are null as the array was not initialized. In the above program, the array myarray is used without instantiation and thus it results in compiler error (commented statement). Hence before using this array, you should instantiate it using new. As mentioned earlier, the first declaration is without size and instantiation. ![]() The above program shows two ways of declaring a String Array. (strArray " " strArray " " strArray " " (myarray) //variable myarray might not have been initialized String strArray = new String //declaration with size String myarray //declaration of string array without size Let’s implement a program that shows a String Array declaration. If you directly print the elements of this array, you will see all the null values as the array is not initialized. Here, a String array ‘myarray’ with five elements is declared. In the second declaration, a String Array is declared and instantiated using new. Note that before using this array, you will have to instantiate it with new. In the first declaration, a String Array is declared just like a normal variable without any size. String myarray //String array declaration without size String myarray = new String //String array declaration with size Given below are the two ways of declaring a String Array. with a size or without specifying the size. Declaring A String ArrayĪ String Array can be declared in two ways i.e. In this tutorial, we will discuss the string array in Java in detail along with the various operations and conversions that we can carry out on string arrays. You can do all the operations on String array like sorting, adding an element, joining, splitting, searching, etc. This is because each element is a String and you know that in Java, String is an object. If you remember, even the argument of the ‘main’ function in Java is a String Array. String array is one structure that is most commonly used in Java. Thus, we can define a String Array as an array holding a fixed number of strings or string values. We can have an array with strings as its elements. ![]()
