All the elements of an array in Java MUST conform to the same data type.

TRUE

Explanation:

The array is allow to store the multiple values but with same data type.

It cannot store element with different data type.

For example:

int array[] = {1, 'b', 8.7, 9, 'z'}

the above is wrong way to declare the array.

the correct ways is:

int array[] = {1,2,3,4};

float array[] = {1.2, 3.4, 9.6};

we can store only same data type element in multiple tiles.
