In Java, division by zero can cause a runtime error known as the ArithmeticException. This exception is thrown when an attempt is made to divide a number by zero. The result of such an operation is undefined in mathematics, and Java reflects this by throwing an exception. To avoid this error, it is important to check for the possibility of division by zero before performing the operation.
There are several ways to check for division by zero in Java. One approach is to use the built-in method Double.isFinite(), which returns false if the number is infinite (including positive or negative infinity) or NaN (Not-a-Number). Another approach is to use the conditional operator to check if the denominator is equal to zero. For example:
