In Java, shortcut arithmetic operators are used to simplify arithmetic operations. For example, the shortcut operator += can be used to add a value to a variable and assign the result to the same variable. This is equivalent to writing x = x + y. Similarly, the shortcut operator -= can be used to subtract a value from a variable and assign the result to the same variable. This is equivalent to writing x = x - y. Other shortcut operators include *=, /=, and %=.
