Java String[] is an array of String objects in Java. It is a collection of strings that can be accessed by index. The String[] array can hold a fixed number of strings, and the size of the array cannot be changed once it is created. The syntax for creating a String[] array is:
String[] arrayName = new String[length];
Here, length is the number of strings that the array can hold. To access the individual elements of the array, you can use the index number starting from 0 to length-1.
For example, the following code creates a String[] array of size 3 and assigns values to its elements:
String[] fruits = new String[3];
fruits[0] = "apple";
fruits[1] = "banana";
fruits[2] = "cherry";
You can also create and initialize a String[] array in one line, like this:
String[] fruits = {"apple", "banana", "cherry"};
The String[] array is widely used in Java programming to store and manipulate strings. It is used in various applications such as text processing, data analysis, and database management.
