java中如何调整jpane的大小和位置？jframe的大小不变的情况下。

Answer 1

JPanel吧？JPanel是透明的，一般不固定大小和位置，而是用布局管理器。
如果想强制大小和位置的话，就把父容器的布局管理器设为null，用
public void setBounds(int x,int y,int width,int height)
//Moves and resizes this component. The new location of the top-left corner is specified by x //and y, and the new size is specified by width and height.
public void setLocation(Point p)
//Moves this component to a new location. The top-left corner of the new location is specified //by point p. Point p is given in the parent's coordinate space.

public void setSize(int width,int height)
//Resizes this component so that it has width width and height height.
