java如何改全屏为窗口？求啊啊啊啊

我们要做游戏大作业，用java在eclipse里做，下了个游戏源代码不过是全屏的，要怎么改才能把它改成窗口的哇。那个源代码里面有关全屏的代码screenmanager.java如下
import java.awt.*;
import java.awt.image.BufferStrategy;
import java.awt.image.BufferedImage;
import java.lang.reflect.InvocationTargetException;
import javax.swing.JFrame;
public class ScreenManager {
private GraphicsDevice device;
/**
Creates a new ScreenManager object.
*/
public ScreenManager() {
GraphicsEnvironment environment =
GraphicsEnvironment.getLocalGraphicsEnvironment();
device = environment.getDefaultScreenDevice();
}

/**
Returns a list of compatible display modes for the
default device on the system.
*/
public DisplayMode[] getCompatibleDisplayModes() {
return device.getDisplayModes();
}

/**
Returns the first compatible mode in a list of modes.
Returns null if no modes are compatible.
*/
public DisplayMode findFirstCompatibleMode(
DisplayMode modes[])
{
DisplayMode goodModes[] = device.getDisplayModes();
for (int i = 0; i < modes.length; i++) {
for (int j = 0; j < goodModes.length; j++) {
if (displayModesMatch(modes[i], goodModes[j])) {
return modes[i];
}
}
}
return null;
}

/**
Returns the current display mode.
*/
public DisplayMode getCurrentDisplayMode() {
return device.getDisplayMode();
}

/**
Determines if two display modes "match". Two display
modes match if they have the same resolution, bit depth,
and refresh rate. The bit depth is ignored if one of the
modes has a bit depth of DisplayMode.BIT_DEPTH_MULTI.
Likewise, the refresh rate is ignored if one of the
modes has a refresh rate of
DisplayMode.REFRESH_RATE_UNKNOWN.
*/
public boolean displayModesMatch(DisplayMode mode1,
DisplayMode mode2)
{
if (mode1.getWidth() != mode2.getWidth() ||
mode1.getHeight() != mode2.getHeight())
{
return false;
}
if (mode1.getBitDepth() != DisplayMode.BIT_DEPTH_MULTI &&
mode2.getBitDepth() != DisplayMode.BIT_DEPTH_MULTI &&
mode1.getBitDepth() != mode2.getBitDepth())
{
return false;
}
if (mode1.getRefreshRate() !=
DisplayMode.REFRESH_RATE_UNKNOWN &&
mode2.getRefreshRate() !=
DisplayMode.REFRESH_RATE_UNKNOWN &&
mode1.getRefreshRate() != mode2.getRefreshRate())
{
return false;
}
return true;

}

Answer 1

这个研究了，半上午，没办法，直接简单的改几行代码，就能变成窗体程序的，
需要重构代码的
把 ScreenManager 重构成 JFrame 或是 剥离开 ScreenManager 直接用 Jframe

如果。只是想简单的 ，变成 窗体，可以
修改 frame.setUndecorated(true) 把这个屏蔽掉

但是，你只是，临时的方法，不推荐，不能解决根本

Answer 2

// 将一个Frame最大化
if (f.isUndecorated()) {// 无边框窗口
   f.setBounds(GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds());
}else{
   f.setExtendedState(f.getExtendedState() | JFrame.MAXIMIZED_BOTH);
}
