This article mainly explains "Error in Java: the solution to Java heap space error". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "Error in Java: the solution to Java heap space error".

According to the answers on the Internet, there are roughly two solutions:

1. Set environment variables

Set JAVA_OPTS=-Xms32m-Xmx512m

You can make changes according to the memory of your machine, but testing this method does not solve the problem. Maybe there's something else that needs to be set up.

2. Java-Xms32m-Xmx800m className

This parameter is added when executing the JAVA class file, where className is the exact class name that needs to be executed. (including package name)

This solves the problem. And the execution speed is much faster than when it is not set up.

If you may use Eclispe when testing, you need to enter the parameter-Xms32m-Xmx800m in VM arguments in Eclipse-> run-arguments.
