What is difference between & and && in Java?

& is a bitwise operator and compares each operand bitwise. It is a binary AND Operator and copies a bit to the result if it exists in both operands. … Whereas && is a logical AND operator and operates on boolean operands. If both the operands are true, then the condition becomes true otherwise it is false.

What does && means?
