The bottom right corner of Eclipse always prompts computing additional info solution

Today do not know what to press, found that the lower right corner of Eclipse has been prompted computing additional info, open progress, which has a few of the same information at the same time, but has been carried out, the Internet to find solutions, found that the original content is used Assist (that is, press ALT +/, will come out code hints) is caused by the function. Eclipse will look for Java source code, first find it locally, and then go to the Internet. Local default is the source code without java. Computing additional info represents the source code for Java in search of the Internet.

Solution One:
1. Locate the Src.zip file in your JDK installation directory;
2. Open the Eclipse:window menu->preference->java->installed JREs;
3. Select the JRE you are using in the list, and then edit;
4. Select Rt.jar, then click on the "Source Attachment" button, select "External file" after the popup dialog, and then associate the Src.zip file in your JDK installation directory with the Rt.jar;
The hint of computing additional info will no longer appear, and when you select the native class or method of the JDK in your code, you can also find the source code for Java by pressing F3.

Solution Two:
Restart eclipse directly does not appear this, I do so, O (∩_∩) o haha ~.
