This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
The following example results in a compiler exception and needs a cast to execute.
For primitives, I know that the result of arithmetic operations with byte and short result in int and need casting to avoid compiler errors. Number literals are by default int and hence in this example a cast is needed. Am I right?
giving a method expecting a short an int will cause compiler error because int which is a 32 bit 2's complement integer can cause overflow if it's stored in short which is only 16bit, however the reverse is ok, you can store short integer in int since int is an extension of short
