Solution to heap space overflow in eclipse

Eclipse
The JVM size is set in the startup parameters, because JVM is also required during eclipse runtime, so the JVM size set in eclipse. INI is not a specific one.ProgramUsed during running
The JVM size, which is irrelevant to the JVM size of the specific program running.

So how can we set the JVM size of a program? (of course, this problem does not exist if the console runs, for example, Java-xms256m-xmx1024m.
Classname, so that the JVM size of the current program can be set )?

The default JVM configuration of a program in eclipse is-xms8m.
-Xmx128m, so we need to manually adjust the memory consumption during processing to avoid memory overflow. The specific setting method is as follows:

Select the running class, click 'run-> Run... 'in the menu, and enter in the VM arguments box under the (x) = argument tab.
-Xmx512m: Save and run it.
