What happens if you exceed the size of an array in Java?

Yes, there limit on java array. Java uses an integer as an index to the array and the maximum integer store by JVM is 2^32. so you can store 2,147,483,647 elements in the array. In case you need more than max-length you can use two different arrays but the recommended method is store data into a file.

What happens if the index of a loop exceeds the defined size of an array in C?

Explanation: If the index of the array size is exceeded, the program will crash. Hence “option c” is the correct answer.

What will happen when you access the array more than its dimension?

Accessing array elements greater than its size If you try to access the array position (index) greater than its size, the program gets compiled successfully but, at the time of execution it generates an ArrayIndexOutOfBoundsException exception.

What happens when an array is initialized with more Initializers as compared to its size?

If the array is longer than the initializer list, the array elements without an explicit initializer are initialized to 0. The number of values in the initializer list may never be greater than the number of elements in the array. But it’s okay if the array is larger than the number of initializer values.

What would happen if you try to put so many values into an array when you initialize it that the size of the array is exceeded?

Answer: The program would throw an error, if it was Java it would probably be a null pointer exception. If you were looping through the array it might overwrite values in the array.

What would happen if you initialize the array with more values than the size of the array?

What would happen if you put too few elements in an array when you initialize it?

Arrays can be created and initialized in one line using the following command: int array Integer[3] = {10,20,30};

Why must we start the array index at 0 instead of 1?

The first element of the array is exactly contained in the memory location that array refers (0 elements away), so it should be denoted as array[0] . Most programming languages have been designed this way, so indexing from 0 is pretty much inherent to the language.

Can we change index of array in Java?

You can use the set() method of java. util. ArrayList class to replace an existing element of ArrayList in Java. The set(int index, E element) method takes two parameters, the first is the index of an element you want to replace, and the second is the new value you want to insert.

What happens when an array is initialized with i fewer Initializers as compared to its size is more initializer as compared to its size?

If there are fewer initializers than elements in the array, the remaining elements are automatically initialized to 0. For example, int a[10] = {0, 1, 2, 3, 4, 5, 6}; would declare, define, and initialize an array b of 5 elements (i.e. just as if you’d typed int b[5]).
