Is string and array same?
Strings and arrays are quite similar except the length of an array is fixed whereas strings can have a variable number of elements. Simply put, an array is a collection of like-type variables whereas a string is a sequence of characters represented by a single data type.
What is array and string in Java?
A String Array is an Array of a fixed number of String values. A String is a sequence of characters. Generally, a string is an immutable object, which means the value of the string can not be changed. The String Array works similarly to other data types of Array. In Array, only a fixed set of elements can be stored.
What is string array with example?
For Example, if you want to store the name of students of a class then you can use the arrays of strings. Arrays of strings can be one dimensional or multidimensional. String[] s2 = new String[4]; Initialization of Arrays of Strings: Arrays can be initialized after the declaration.
What are the use cases for using the arrays and strings in the programs?
They are used to store similar types of elements as in the data type must be the same for all elements. They can be used to store the collection of primitive data types such as int, float, double, char, etc of any particular type.

Can array hold strings?
As previously stated, arrays can hold a collection of virtually any data type, therefore they can also be used to store a collection of strings. Arrays that hold string data types are called String arrays in Java.
What is a char array in C?
This is primarily because “char” is the keyword in languages such as C that is used to declare a variable of the scalar character data type. A char array is a sequence of characters recorded in memory in a long line of consecutive addresses that can be quickly accessed by using the index of an element within the array.
