Can you use += in Java?

Let’s understand the += operator in Java and learn to use it for our day to day programming. x += y in Java is the same as x = x + y. It is a compound assignment operator. Most commonly used for incrementing the value of a variable since x++ only increments the value by one.

What is the difference between i i 1 and i += 1?

i += i means the i now adds its current value to its self so let’s say i equals 10 using this += expression the value of i will now equal 20 because you just added 10 to its self. i +=1 does the same as i=i+ 1 there both incrementing the current value of i by 1.
