In this core java tutorial we will Find Total Amount Of Memory In JVM (Java virtual machine) In your System
in java.

About totalMemory() method of java.lang.Runtime class in java >
  • totalMemory() method of Runtime class returns the total amount of memory in the JVM (Java virtual machine).
  • totalMemory() is the native method in java, so value returned by this method depends on the host environment.


Example/program to Find Total Amount Of Memory In
JVM (Java virtual machine) In your System >
/**

public class TotalAmountOfMemoryInJavaVirtualMachineExample{
   public static void main(String[] args) {
         
     /**
     * first we will get the java Runtime object using the
     * Runtime class's getRuntime() method in java.
     */
       Runtime runtime = Runtime.getRuntime();
     
     /**

     long totalMemoryInJVM = runtime.totalMemory();
      
       System.out.println("Total amount of memory in the "
             + "JVM (Java virtual machine) in bytes = "+ totalMemoryInJVM);
   }
}
/* output
Total amount of memory in the JVM (Java virtual machine) in bytes = 257425408
