2)

3)

Which of the following is something not specified in the Manifest file of an Android application O Declarations for activities instantiated in program O Permissions the application must have in order to run O Private key for secure installation The minimum level of the Android API that the application requires

Solution

Answer:

1) Permissions the application must have in order to run , because permissions need not specified in manifest file.

2) Pass as value to a method , in java, you cannot control whether you want to pass by value or pass by reference. In c++, even if the variable holds reference, you can get the value by using * symbol.

3) Yes ,

If you pass anything by reference, if you change the value in the function, it will reflect outside the function.

In java, array and object are pass by reference. But primitive types like int, float, bool are pass by value.So if you pass an int into a function, changing the value of that int inside the function will not reflect the value outside once the function is executed.
