To check if all of the values in an array are equal to null , use the every() method to iterate over the array and compare each value to null , e.g. arr. every(value => value === null) . The every method will return true if all values in the array are equal to null .
To check if an given array is empty or not, we can use the built-in Array. Length property in C#. Alternatively, we can also use the Array. Length property to check if a array is null or empty in C#.
Primitive arrays (int, float, char, etc) are never "empty" (by which I assume you mean "null"), because primitive array elements can never be null. By default, an int array usually contains 0 when allocated.
int is a primitive type in java, and cannot be null. Only objects can be null.
Elements in primitive arrays can't be empty. They'll always get initialized to something (usually 0 for int arrays, but depends on how you declare the array).
If you declare the array like so (for example):
int [] myArray ;
myArray = new int[7] ;
then all of the elements will default to 0.
An alternative syntax for declaring arrays is
int[] myArray = { 12, 7, 32, 15, 113, 0, 7 };
where the initial values for an array (of size seven in this case) are given in the curly braces {}.
