As a popular programming language, Java is widely used in various fields. But in the process of using Java, you may encounter various errors. One of the common errors is Java12 Compact Number Formatting error. This article will introduce the causes of this error, how to deal with it and avoid it.

1. Cause of the error

Java12 Compact Number Formatting error is due to the introduction of a new feature in Java12, namely Compact Number Formatting (Compact Number Formatting). This feature is designed to improve the efficiency and expressiveness of digital formatting. However, if the application uses illegal syntax or unsupported options when using compact number formatting, a Java12 Compact Number Formatting error will occur.

2. Processing method

When a Java12 Compact Number Formatting error occurs, you need to do the following:

1. Check the code

First , you need to check the code to find out where the error is caused. Typically, this error occurs in code that formats numbers.

2. Modify the code

Once the error is found, the code needs to be modified to meet the requirements of compact number formatting. For example, if an unsupported option is used, it can be removed or replaced with a supported option. If illegal syntax is used, it can be corrected according to the rules of compact number formatting.

3. Use a compatible Java version

If you cannot modify the code or want to avoid this error, you may consider using a compatible Java version. Some older versions of Java may not support compact number formatting, but this error will not occur. Therefore, these versions can be used to avoid problems.

3. Avoidance methods

In addition to dealing with Java12 Compact Number Formatting errors, you can also take the following measures to avoid this error:

3. Follow formatting rules

If you want to format numbers in Java, you need to follow formatting rules. Only by formatting according to the rules can errors be avoided.

Summary:

Java12 Compact Number Formatting error is a common problem in the Java programming process. To avoid and handle this error, you need to become familiar with the syntax and options of compact number formatting, follow the formatting rules, and use supported options. If you cannot avoid this error, you need to modify the code or use a compatible Java version. While this error may cause some inconvenience and trouble, it can be easily handled and avoided from happening again as long as you take appropriate measures.
