How to Increase JVM Heap Size to Resolve OutOfMemoryError?

Increasing JVM Heap Size for OutOfMemoryError Resolution

When encountering the "java.lang.OutOfMemoryError: Java heap space" exception, it indicates that the JVM's heap memory has been exceeded. To resolve this issue, it is necessary to increase the heap size.

To adjust the heap size, the following command-line arguments can be used:

• -Xms: Initial Java heap size
• -Xmx: Maximum Java heap size
• -Xss: Java thread stack size

In your specific scenario, you need to increase the maximum heap size (-Xmx). The following example demonstrates how to allocate 256MB for the heap:

java -Xmx256m TestData.java

By implementing these changes, you should be able to avoid the OutOfMemoryError and allow your application to operate without encountering heap size limitations.
