How to Increase Heap Size of JVM

Problem:

An error occurs due to insufficient memory space in the Java heap, leading to an "OutOfMemoryError."

Solution:

To resolve this issue, the heap size of the Java Virtual Machine (JVM) needs to be increased. Here are the parameters that can be used:

• -Xms: Sets the initial Java heap size.
• -Xmx: Sets the maximum Java heap size.
• -Xss: Sets the Java thread stack size.

Example:

To increase the maximum heap size to 256 megabytes, the following command can be used:

java -Xmx256m TestData.java

By modifying these parameters, the heap size can be adjusted to accommodate the resource requirements of the application and prevent out-of-memory errors.
