问题
I'm trying to compile my Java program, however I am getting a "Deprecated File" error.
I normally compile the file by typing "Javac FileName.java", however I get an error saying:
FileName.java uses or overrides a depreacted API. Recompile with Xlint-deprecation for details.
What do I type into the command line to make it run?
回答1:
It's not an error, just a warning.
The compiler will still produce a class file and you will be able to run it. However, it's a good idea to address the warning, since using deprecated API could lead to more problems later on.
If you choose to see the warnings, you can do this:
javac -Xlint:deprecation FileName.java
回答2:
If you don't have a deprecation
javac -Xlint Filename.java

I was getting the same exception in running a gradlew build. I discovered that the path included Java 1.7 and my JAVA_HOME variable path had 1.8 specifed. Once I updated the path to 1.8, the build was successful.

Had the similar issue and setting the PATH to the correct file that contains the JDK worked. For windows, search environnement variables > select edit environnement variables > Enter JAVA_HOME as variable and set the value to the jdk file.
