Java Array to List Issue

java

Solution

What you get is not a list of integers but a list of integer arrays, i.e. `List<int[]>`. You can't create collections (like `List`) of primitive types.

In your case, the `lis.contains(20)` will create an `Integer` object with the value 20 and compare that to the int array, which clearly isn't equal.

Try changing the type of the array to `Integer` and it should work:

Integer a[] = new Integer[] {20, 30} ;
List lis = Arrays.asList(a) ;
System.out.print(lis.contains(20));

Problem

I have following Java code, ``` int a[] = new int[] {20, 30} ; List lis = Arrays.asList(a) ; System.out.print(lis.contains(20)); ``` However, output is false. Can anybody help me, why this is not giving True ?
