//we are going to see only one dimensional arrays

//As we all know to write any code the program should have main function 
//I created call called Arrays

        // Here i directly created an one dimensional array andi also given the values 
        int a[]={1,2,3,4,5} ;
        //first index always starts with 0 and last index always ends with size -1
        
        // To print the elements in Array we use loop function 
        for(int i=0;i<5;i++){
        System.out.println(a[i]);
        }
        
        //The length will always last index+1
        // To find the length of the array we also use loop function
        for(int i=0;i<5;i++){
