用java设计一个程序,要求如下: 1、进攻方有若干基地,位于不同位置,每个基地有若干战机; 2、防守方有若干目标,位于不同位置; 3、战机有最大往返次数,超过这个上限,战机不能继续参战; 4、战机往返目标一次,记为一次攻击,每次往返有被击落的概率; 5、每个目标有最大承受攻击的次数,超过这个次数,目标被摧毁; 6、随机产生若干基地,若干目标,若干战机,设计算法按照最有效的攻击策略安排战机对目标攻击; 7、所有目标被摧毁,或所有战机不能参战(包括被击落),程序结束。

这是一个比较复杂的程序设计问题,需要考虑很多因素,包括战机的数量、基地和目标的位置、战机的往返次数、被击落的概率以及目标的承受攻击次数等等。下面是一个简单的Java程序框架,用于实现这个问题的解决方案:
```java
import java.util.ArrayList;
import java.util.List;
import java.util.Random;
class Base {
private int id;
private int x;
private int y;
private List<Plane> planes;
public Base(int id, int x, int y) {
this.id = id;
this.x = x;
this.y = y;
this.planes = new ArrayList<>();
}
public int getId() {
return id;
}
public int getX() {
return x;
}
public int getY() {
return y;
}
public List<Plane> getPlanes() {
return planes;
}
public void addPlane(Plane plane) {
planes.add(plane);
}
}
class Target {
private int id;
private int x;
private int y;
private int maxAttacks;
private int currentAttacks;
public Target(int id, int x, int y, int maxAttacks) {
this.id = id;
this.x = x;
this.y = y;
this.maxAttacks = maxAttacks;
this.currentAttacks = 0;
}
public int getId() {
return id;
}
public int getX() {
return x;
}
public int getY() {
return y;
}
public int getMaxAttacks() {
return maxAttacks;
}
public int getCurrentAttacks() {
return currentAttacks;
}
public void attack() {
currentAttacks++;
}
public boolean isDestroyed() {
return currentAttacks >= maxAttacks;
}
}
class Plane {
private int id;
private Base base;
private Target target;
private int maxRoundTrips;
private int currentRoundTrips;
private double hitProbability;
public Plane(int id, Base base, Target target, int maxRoundTrips, double hitProbability) {
this.id = id;
this.base = base;
this.target = target;
this.maxRoundTrips = maxRoundTrips;
this.currentRoundTrips = 0;
this.hitProbability = hitProbability;
}
public int getId() {
return id;
}
public Base getBase() {
return base;
}
public Target getTarget() {
return target;
}
public int getMaxRoundTrips() {
return maxRoundTrips;
}
public int getCurrentRoundTrips() {
return currentRoundTrips;
}
public double getHitProbability() {
return hitProbability;
}
public void fly() {
currentRoundTrips++;
if (currentRoundTrips > maxRoundTrips) {
return;
}
if (new Random().nextDouble() > hitProbability) {
return;
}
target.attack();
if (target.isDestroyed()) {
return;
}
fly();
}
public boolean isAvailable() {
return currentRoundTrips < maxRoundTrips;
}
}
public class AttackSimulation {
private List<Base> bases;
private List<Target> targets;
private List<Plane> planes;
public AttackSimulation(int numBases, int numTargets, int numPlanes) {
bases = new ArrayList<>();
targets = new ArrayList<>();
planes = new ArrayList<>();
for (int i = 0; i < numBases; i++) {
bases.add(new Base(i, new Random().nextInt(100), new Random().nextInt(100)));
}
for (int i = 0; i < numTargets; i++) {
targets.add(new Target(i, new Random().nextInt(100), new Random().nextInt(100), new Random().nextInt(10) + 1));
}
for (int i = 0; i < numPlanes; i++) {
Base base = bases.get(new Random().nextInt(numBases));
Target target = targets.get(new Random().nextInt(numTargets));
planes.add(new Plane(i, base, target, new Random().nextInt(10) + 1, new Random().nextDouble()));
base.addPlane(planes.get(i));
}
}
public void simulate() {
while (true) {
boolean noMorePlanes = true;
for (Base base : bases) {
for (Plane plane : base.getPlanes()) {
if (plane.isAvailable()) {
noMorePlanes = false;
plane.fly();
}
}
}
if (noMorePlanes) {
break;
}
boolean allTargetsDestroyed = true;
for (Target target : targets) {
if (!target.isDestroyed()) {
allTargetsDestroyed = false;
}
}
if (allTargetsDestroyed) {
break;
}
}
}
}
```
这个程序包括三个类:`Base`,`Target` 和 `Plane`,分别表示基地、目标和战机。其中,`Base` 类包括基地的编号、位置和所属的战机;`Target` 类包括目标的编号、位置、最大承受攻击次数和当前已经承受的攻击次数;`Plane` 类包括战机的编号、所属基地、攻击目标、最大往返次数、当前已经往返的次数和被击落的概率。
除了这三个类之外,还有一个 `AttackSimulation` 类,用于模拟攻击过程。在构造函数中,随机生成了若干个基地、目标和战机,并将它们存储在 `bases`、`targets` 和 `planes` 列表中。在 `simulate` 方法中,每个战机依次执行 `fly` 方法,如果战机的往返次数超过了最大值,或者被击落了,就不能再参战了。如果所有战机都不能参战,程序结束;如果所有目标都被摧毁了,程序也结束。
这只是一个简单的框架,实际上你还需要进一步完善程序,例如考虑如何安排战机对目标的攻击策略,以及如何评估攻击的效果等等。
