Hi Friend,

1)public class Example{
public static void main(String[]args){
int list[]=new int[5];
for (int i = 0; i < 5; i++){
list[i] = 2 * i + 5;
if (i % 2 == 0){
list[i] = list[i] - 3;
System.out.println(list[i]);
}
}
}
}

Output of above code is:
2
6
10

Explanation-In the above code, firstly the array stores the value of i after multiplying with 2 and adding with 5.
If the value of i after dividing it with 2 results 0 then subtract this array value by 3.


2)public class Example{
public static void main(String[]args){

int count;
int[] alpha = new int[5];
alpha[0] = 5;
for (count = 1; count < 5 ; count ++){
alpha[count] = 5 * count + 10;
alpha[count - 1] = alpha[count] - 4;
}
System.out.println("List elements: ");
for (count = 0; count < 5; count++)
System.out.println(alpha[count] + " ");
}
}

Output of above is:
11
16
21
26
30

Expalanation- Here you have declared the first value of array.Firstly the array stores the value of count after multiplying with 5 and adding with 10. And then subtract this array value by 4 and store in the previous array index. This will continue till you will get all the array values.
