java byte array memory not released -

-

As long as I have set the indicator to zero, why does memory usage increase every time I press the button? (Code Attach)

This continues my program memory usage continues

thanks. package newHashFunction; Import java.awt.event.ActionEvent; Import java.awt.event.ActionListener; Import javax.swing.JButton; Import javax.swing.JFrame; Public Category Memory_not_released JFrame Expands {/ ** * @param args * / public static void main (string [] args) {// TODO auto generated method stub Memory_not_released memory_not_released = new Memory_not_released (); } Memory_not_released () {button button 1 = new pocket ("make byte"); Button1.addActionListener (New Exhibitist) {@ Override Public Voice ActionPerfect (Action Event E) {// Todo Auto-Generated Method Stub Byte [] Byte 1 = New Byte [10000000]; Byte 1 = Faucet;}}) ; (Button1) add; This.pack (); SetVisible (true); This.setDefaultCloseOperation (EXIT_ON_CLOSE); }}

continue setting its variable to null Does not happen. Memory is issued only when the garbage collector decides that any other operation requires storage and should be recovered.

It is entirely possible that the memory never will continue, even then the garbage collector has run several times.

Update

I think I understand why your worries are coming from time to time for release of memory. In Java, memory is allocated on stack whether you know it or not, Java is configured with maximum heap size (you can specify this maximum on the command line). Suppose Java is running with the size of the maximum pile of 100 MB. Now, suppose the reason for allocation in your program is 5 MB. The operating system uses Java (approximately 5 MB) because all Java has requested the operating system at that time. As your program runs, the maximum memory will be continued to reach the maximum heap size (100 MB) at that time, at that time most of the garbage collectors will be more aggressive in their memory release. Until then, many garbage collectors can not easily bother leaving the memory.

Therefore, you do not need to worry about the maximum memory from your operating system.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
