Important of an array example

Program Code

class ArrayDemo{
     public static void main(String args[]){
        int array[] = new int[7];

        for (int count=0;count&lt;7;count++){
           array[count]=count+1;
       }
       
       for (int count=0;count&lt;7;count++){
           System.out.println("array["+count+"] = "+array[count]);
       }

    }
}

Output

array[0] = 1
array[1] = 2
array[2] = 3
array[3] = 4
array[4] = 5
array[5] = 6
array[6] = 7

Explanation

Save , Compile & Run the code. Observe the Output. If x is a reference to an array, x.length will give you the length of the array. Unlike C, Java checks the boundary of an array while accessing an element in it. Java will not allow the programmer to exceed its boundary.

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
