It won't resize automatically. Arrays in general is a very useful and important data structure that can help solve many types of problems. In our subsequent tutorials, we will discuss multi-dimensional arrays in Java. In the following example, we will iterate over elements of String Array using Java For Loop. To initialize a string array, you can assign the array variable with new string array of specific size as shown below. Another syntax to declare and initialize a String array together is by using the new operator. Elements of no other datatype are allowed in this array. Java 8 provides another simple approach to convert list of string to array of string. The return type of a method must be declared as an array of the correct data type. Let’s look at the below program to sort an array in Java in ascending order. The next method to convert the string into a string array is by using regular expressions. String[] myarray = new String[5];//String array declaration with size. As it is present, an appropriate message is displayed. In the case of the ‘for’ loop, you need to specify the start and end condition. The output of the above program shows the original input array as well as the output array that is sorted alphabetically. Here, you will compare each element in the String Array with the string to be searched. 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. Given below is an example of using patterns to convert string to String Array. Hence before using this array, you should instantiate it using new. A string array can be initialized by using: //inline initialization String[] stringArray1 = new String[] {"R","S","T"}; String[] stringArray2 = {"R","S","T"}; //initialization after declaration String[] stringArray3 = new String[3]; stringArray3[0] = "R"; stringArray3[1] = "S"; stringArray3[2] = "T"; This will create a string array in memory, with all elements initialized to their corresponding static default value. As I wrap up my collection of “Java String array” tutorials, here are a few links to my other String array tutorials: Java String array examples; How to create an array in Java; Java String array - find the longest String in an array; How to create a String array in Java The default value for a string is empty string “”. In the above program, we have a string array that contains the numbers as strings. In this method, you create a new array having a size that is greater than the original array so that you can accommodate the new element. Java String Array Examples. Once the String Array is initialized, you can use it in your program normally. The syntax of creating an array in Java using new keyword − type[] reference = new type[10]; That’s all about converting byte array to String in Java. There are various ways using which you can iterate String array. Given below is a Java program that uses asList. Thus, after the declaration, we proceed to initialize the array. Below are the steps: 1. We can use any of these looping statements like For Loop or While Loop to iterate over elements of a Java Array. Java example to convert string into string array using String.split() method and using java.util.regex.Pattern class. And in the following example, we will use Java for-each loop, to iterate over elements of string array. In the above program, the pattern that we have specified is a space character. Any changes were done to string results in a new string. Step 2: Create a character array of the same length as of string.
