❌ A. num1 == num2 and num3 == num4 ✅ B. num1 == num2 and num3 != num4 ❌ C. num1 != num2 and num3 == num4 ❌ D. num1 != num2 and num3 != num4 ❌ E. The code does not compile ❌ F. A runtime exception is thrown
Explanation: We always thought that whenever two object references are compared using “==”, it always evaluates to “false”. But here Integer caching changes the results. Integer class has a caching range of -128 to 127. Whenever a number is between this range and autoboxing is used, it assigns the same reference. That’s why for value 100, both num1 and num2 will have the same reference, but for the value 500 (not in the range of -128 to 127), num3 and num4 will have different reference.

How Does Bitcoin Work?
Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
