When comparing arrays in Java, are there any differences between the following 2 statements? Object[] array1, array2; array1.equals(array2); Arrays.equals(array1, array2); And if so, what are they?
Arrays contain a specific number of elements of a particular type. So that the compiler can reserve the required amount of space when the program is compiled, you must specify the type and number of elements that the array will contain when it is defined.
How do I convert an array to a list in Java? I used the Arrays.asList() but the behavior (and signature) somehow changed from Java SE 1.4.2 (docs now in archive) to 8 and most snippets I found on t...
In Java, Arrays.equals() allows to easily compare the content of two basic arrays (overloads are available for all the basic types). Is there such a thing in C#? Is there any "magic" way of compar...
My function takes float values given in a 6-dim NumPy array as input. What I tried to do initially was this: First, I created a function that takes two arrays and generate an array with all combinations of values from the two arrays:
If I alter the test arrays to two sequences from 0 to 99 then I get results similar to this, Concat took 45945ms CopyTo took 2230ms BlockCopy took 1689ms From these results I can assert that the CopyTo and BlockCopy methods are significantly more efficient than Concat and furthermore, if performance is a goal, BlockCopy has value over CopyTo.
Arrays.toString As a direct answer, the solution provided by several, including @Esko, using the Arrays.toString and Arrays.deepToString methods, is simply the best. Java 8 - Stream.collect (joining ()), Stream.forEach Below I try to list some of the other methods suggested, attempting to improve a little, with the most notable addition being the use of the Stream.collect operator, using a ...
7 Arrays in C are converted, in most of the cases, to a pointer to the first element of the array itself. And more in detail arrays passed into functions are always converted into pointers. Here a quote from K&R2nd: When an array name is passed to a function, what is passed is the location of the initial element.
var array3 = ["Vijendra","Singh","Shakya"]; The output array should have repeated words removed. How do I merge two arrays in JavaScript so that I get only the unique items from each array in the same order they were inserted into the original arrays?
