Use -Xmx to specify the maximum heap size to control RAM usage in Java programs. The -Xms parameter sets the initial heap size, and -Xss defines the thread stack size.
Setting the maximum Java heap size with -Xmx can help resolve Java heap size error messages. Limiting memory allocation using -Xmx64m corrected a low-memory issue during program execution.
Configuring Java programs with -Xmx64m restricts memory usage, suitable for Raspberry Pi with memory constraints. Setting RAM limits prevents VM initialization errors and ensures program functionality.
Adjust Java program memory usage by specifying -Xmx with values like -Xmx64m or -Xmx1G. Command-line parameters like -Xms, -Xmx, and -Xss give granular control over memory allocation in Java applications.
