Netbeans 8.2 with jdk 9 Code Answer

Hello Developer, Hope you guys are doing great. Today at Tutorial Guruji Official website, we are sharing the answer of Netbeans 8.2 with jdk 9 without wasting too much if your time.

The question is published on by Tutorial Guruji team.

I have an issue on hdpi with netbeans, the icon become too small when I open it. Then I found the issue below. And someone says that jdk9 fix the resolution problem.

Here is my environment:

  • OS: windows 10 (64bit)
  • JDK: JDK9 BUILD149
  • netbeans 8.2

I downloaded jdk9 & netbeans8.2 on windows10, hoping that JDK9 might fix the annoying resoution issue. Unfortunately, I can’t open the netbeans.

After I type this in cmd. netbeans.exe --jdkhome "C:Program FilesJavajdk-9" console show the error.

No way to find original stream handler for jar protocol
