📚 Topic Summary
In Java, the assignment operator (=) is used to assign a value to a variable. It evaluates the expression on the right-hand side and assigns the result to the variable on the left-hand side. There are also compound assignment operators (+=, -=, *=, /=, %=) that combine an arithmetic operation with assignment, providing a shorthand way to modify the value of a variable. Understanding these operators is fundamental for writing efficient and readable Java code.
For example, the statement `x = 5;` assigns the integer value 5 to the variable x. Similarly, `x += 3;` is equivalent to `x = x + 3;`, adding 3 to the current value of x and updating x with the new value. Mastering assignment operators is crucial for manipulating data and controlling program flow in Java applications.

✍️ Part B: Fill in the Blanks
Complete the following paragraph with the correct terms:
The __________ operator in Java is denoted by the symbol ‘=’. It is used to __________ a value to a __________. Compound assignment operators like __________ provide a shorthand notation for combining an arithmetic operation and __________. For example, `x += 5` is equivalent to `x = x + 5`.
🤔 Part C: Critical Thinking
