Single Dimensional Array:
A single-dimensional array is a structure that is represented along the X-axis by using several variables with the same name having different subscripts. A single-dimensional array is also called a single subscripted variable.
Creating a Single Dimensional Array
Note: Syntax: <Data type><variable>[] = new <Data type><Number of values to be stored>
For Example: int m[10] = new int[10]. Array elements can be accessed by
Syntax: <array name> <subscript>. For example, m[l] means the element of 'm' at first subscript.
Assigning Data in a 1 D Array
- By using the assignment statement: the data values are defined within the program itself. It may be an integer, a String, a char or a float type. For Example: int m[ ] = {15,7,22,12,34,45,23,31,27,40};
- By using the BlueJ System: In this method, the data values are to be entered at the time of execution of the program. Here the array is declared, but the values are entered during execution by the user. Syntax: public static void main(int m[ ])
- By using the lnputStreamReader class: The data values are to be entered at the time of executing the program. It may be any primitive datatype. Syntax: int m[ ]= new int[IO] ; it creates locations in the memory to store 10 different integer numbers.
- By using Scanner Class: Import “java.util.*”, create a “Scanner” object, then declare “int arr[] = new int[5];”.
