public void setBounds(int x,int y,int width,int height):移动组件并调整其大小。由 x 和 y 指定左上角的新位置,由 width 和 height 指定新的 。
举一反三
- Rectangle类中的成员变量有( )和( ) public class Rectangle{ int width; int height; public void setWidth(int x){ width = x; } public void setHeight(int y){ height = y; } public void show(){ System.out.println("宽:"+width",高:"+height); } }
- 【多选题】已知代码如下 class Rectangle { private int width, height; public void setSize(int width, int height) { this.width = width; this.height = height; } } 下面哪些代码重载 setSize 方法 (10.0分) A. protected void setSize(int width, int height) { this(width, height) } B. public void setSize(int width, float height) { this.width = width; this.height = (int)height; } C. protected void setSize(int width) { this.width = width; } D. public void setSize(int height, int width) { this.width = width; this.height = height; }
- 有以下定义: class Box{ int width,length,height; public: void set(int x=0,int y=0,int z=0) {width=x;length=y;height=z;} }; Box *box; 则以下哪种使用是正确的___
- 阅读下列程序,写出程序运行的结果:class Cube{int width;int height;int depth;Cube(int x,int y,int z){this.width=x;this.height=y;this.depth=z;}public int vol(){return width*height*depth;}}public class UseCube {public static void main(String[] args) {Cube a=new Cube(3,4,5);System.out.println("长度="+a. width);System.out.println("体积="+a.vol());}}
- 类Rectangle中,width和height称为( )变量或( )变量。 public class Rectangle{ int width; int height; public void show(){ System.out.println("宽:"+width",高:"+height); } }
