高分求Java编程题目三题,
1．
已知Point 类定义(声明)如下：
public class Point {
private int x;
private int y;
public Point()
{
}
public Point( int xValue,int yValue )
{
x = xValue;
y = yValue;
}
public void setX( int xValue )
{
x = xValue;
}
public int getX()
{
return x;
}
public void setY( int yValue )
{
y = yValue;
}
public int getY()
{
return y;
}
public String toString()
{
return "[" + x + "," + y + "]";
}
}
不使用继承,设计一个圆类(Circle),要求：该类具有三个私有int 成员：圆心坐标x 和y,
半径radius,相应的Sets 和Gets 方法,计算圆周长(zhouChang)和面积(mianJi)的方法及toString
方法.
2.编写程序,求5 + 10 + 15 + .+ 100,并输出其结果
3.下面的程序完成求两个数的最大值并输出,填写适当的语句.
public class triMax {
public static void main( String[] args ) {
int max,a,b;
a = 10; b = 18;
_________;
if ( max < b )__________ ;
System.out.println( “Max=” + max );
}
}
