What you want to ask is what caused the digital overflow oraclejava to start? The reasons are data type mismatch and operation error.

1, data type mismatch: Please ensure that the variable type used can accommodate the number of the operation. For example, if you use int type to store numbers beyond its range, it will lead to overflow. Consider using a wider range of data types, such as long or BigInteger.

2. Operation error: check the mathematical operation in the code to ensure that there is no wrong operation. For example, operational errors such as division by zero or multiplication overflow can lead to overflow. Use conditional statements or exception handling to avoid these problems.
