Solution 1:

By default, eclipse sets these access-restricted APIs as error.
Windows-> preferences-> JAVA-> compiler-> errors/warnings->
Deprecated and trstricted API-> forbidden reference (access rules):-> change to warning

Solution 2:
You only need to remove the JRE System Library first in the Project Build path, and then add the library JRE system library. After re-compilation, everything will be normal.(I have used this method only, but I do not like other methods)

Solution 3:

Right-click the project-> project properties-> JAVA builder path-> libraries tag, click access rules in the JRE system library, and add sun/** to accessible. If this option exists, edit.

Solution 4:

Windows-> preferences-> JAVA-> installed jres-> select JDK for use-> edit-> Add external jars

I tried 1, 4 feasibility... I am only mine. I have not studied the specific differences. Who has the research to send a message?
