Arrays in Java basics for selenium


1. We can assign value to an element in array as shown below:

testing[3] = 43; or all the elements can be defined in a go like shown below:
int[] testing1= {10,20,30,40,50,60,70,80,90,100};

2. We can extract all the values in an array using for each loop as shown below:

 int[] testing1 = { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 };
 for (int test : testing1) {
     System.out.println(test);
 }

3. The same information can be extracted using for loop can be found as shown below:

for (int i = 0; i < testing1.length; i++) {
     System.out.println(testing1[i]);
 }

4. Using length property, we can find the size of any array


e.g. System.out.println(testing1.length)

4. We can pass an array as a parameter to a method, and also return value from a method:

5. We can sort an array in ascending order using sort();

Arrays.sort(testing1);

6. We can fill values in all the array elements using fill() menthod 
Arrays.fill(testing1, 385);

7. We can compare two arrays using arrays.equals

boolean isArrSame = Arrays.equals(testing1, testing);
System.out.println(isArrSame);
