Java Data Types Exercises A Collection Of Practice Problems And The flag xmx specifies the maximum memory allocation pool for a java virtual machine (jvm), while xms specifies the initial memory allocation pool. this means that your jvm will be started with xms amount of memory and will be able to use a maximum of xmx amount of memory. for example, starting a jvm like below will start it with 256 mb of memory and will allow the process to use up to 2048 mb. In java, == and the equals method are used for different purposes when comparing objects. here's a brief explanation of the difference between them along with examples: == operator: the == operator is used for reference comparison. it checks whether two references point to the exact same object in memory. example:.

The java jargon uses the expression method, not functions in other contexts there is the distinction of function and procedure, dependent on the existence of a return type, which is required in a ternary expression.
