Java reports that the Java version is deprecated even though the latest version is installed
Java reports that the Java version is deprecated even though the latest version is installed Since I updated my Window version to Windows 10 an old Java programm doesn't start, instead I got a Java report that the Java version is deprecated. Now I updated Java to the latest version but the error still occurs. The Java programm was written with Java 4 and I'm using the latest Windows and Java version. Does anyone know a solution? Any concrete error message? Maybe old Java API is either deprecated or removed that you used in your program. – Glains Jun 29 at 8:18 Maybe the JavaSE wasn't installed or no environment variable? But without error, it's hard to help. – KeyMaker00 Jun 29 at 8:42 ...
