Language: Java, Expertise: Advanced - Java allows you to start the application with memory specifications as required.

After successive development exposure, we understand the memory needs of our application. Java allows you to start the application with memory specifications as required and the application is bound to use the specification and work.

java -Xms20m -Xmx1G MemoryViewAdvanced

Please note the arguments -Xms and -Xmx. Here Xms is the initial heap size that the JVM can use to start with and Xmx will the maximum heap size that this contextual JVM can use. These values can be effectively used to manage memory as required.

Code snippet:

public class MemoryViewAdvanced
   public static void main(String args[])
      MemoryViewAdvanced memoryViewAdvanced = new MemoryViewAdvanced();
   private void proceed()
      //Total memory available for the jvm
      System.out.println("Runtime.getRuntime().totalMemory(): " + Runtime.getRuntime().totalMemory());
      //Free memory available
      System.out.println("Runtime.getRuntime().freeMemory(): " + Runtime.getRuntime().freeMemory());
      //Max memory available in the System
      System.out.println("Runtime.getRuntime().maxMemory(): " + Runtime.getRuntime().maxMemory());
