// Syntax: data_type[] variable_name = new data_type[size];
// Decalring array of integers of length 5
int[] intArr = new int[5];
// Declaring array of strings of length 5

// We can also populate the array, if we know the elements in advance
int[] evenDigits = new int[] {0,2,4,6,8}; // notice that in this, we don't need explicit size declaration.
