我正在创建一个简单的JFrame窗口并检查Windows任务管理器的内存使用情况,并且当我尝试使用鼠标指针调整JFrame大小而不是最大化按钮时,它会从51,000增加大量内存k到400,000k,它永远不会下降,但当我使用最大的按钮,它甚至没有增加内存。调整JFrame的大小添加大量内存
是什么导致它增加大量的内存,它永远不会停机?
Image bg = new ImageIcon(getClass().getResource("circle.png")).getImage();
JFrame jf = new JFrame("MySqlConnections");
jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jf.setSize(400,400);
jf.setIconImage(bg);
new ConnectMysql(jf);
jf.setLocationRelativeTo(null);
jf.setPreferredSize(new Dimension(xFrame, yFrame));
jf.setMinimumSize(jf.getPreferredSize());
jf.setVisible(true);
public static void main(String[] args) {
new MainFrame();
/* Total number of processors or cores available to the JVM */
System.out.println("Available processors (cores): " +
Runtime.getRuntime().availableProcessors());
/* Total amount of free memory available to the JVM */
System.out.println("Free memory (bytes): " +
Runtime.getRuntime().freeMemory());
/* This will return Long.MAX_VALUE if there is no preset limit */
long maxMemory = Runtime.getRuntime().maxMemory();
/* Maximum amount of memory the JVM will attempt to use */
System.out.println("Maximum memory (bytes): " +
(maxMemory == Long.MAX_VALUE ? "no limit" : maxMemory));
/* Total memory currently in use by the JVM */
System.out.println("Total memory (bytes): " +
Runtime.getRuntime().totalMemory());
/* Get a list of all filesystem roots on this system */
File[] roots = File.listRoots();
/* For each filesystem root, print some info */
for (File root : roots) {
System.out.println("File system root: " + root.getAbsolutePath());
System.out.println("Total space (bytes): " + root.getTotalSpace());
System.out.println("Free space (bytes): " + root.getFreeSpace());
System.out.println("Usable space (bytes): " + root.getUsableSpace());
}
}
这将有很多与你在做什么,当框架调整大小。你能否提供演示问题的示例代码... – MadProgrammer 2013-05-12 07:24:59
