在这个程序中,我创建了一个LinkedList('lettersLeft')
,其中我添加了Letters
('Letters'是一个类)。每个字母有3个值:1)这是那个字母(即'A') ,2)它在游戏中出现的次数(即'9'),3)你得到的分数(即'1')。另外,getNextLetter()
我从包里得到下一个随机字母。我想制作一个for循环,它会从包中打印出2个随机字母及其值(即“A,9,1 D,4,2”)。这是我的代码(如果你不明白的话请问)
Letters_bag :
public class Letters_bag {
public static final Letters A = new Letters('a', 9, 1);
public static final Letters B = new Letters('b', 2, 3);
public static final Letters C = new Letters('c', 2, 3);
public static final Letters D = new Letters('d', 4, 2);
public static final Letters E = new Letters('e', 12, 1);
public static final Letters F = new Letters('f', 2, 4);
public static final Letters[] allLetters = new Letters[] {
Letters_bag.A,
Letters_bag.B,
Letters_bag.C,
Letters_bag.D,
Letters_bag.E,
Letters_bag.F,
};
LinkedList<Letters> lettersLeft = new LinkedList();
public Letters_bag() {
// add all the letters
addLetter(A);
addLetter(B);
addLetter(C);
addLetter(D);
addLetter(E);
addLetter(F);
}
// helper method to add the letters
private void addLetter(Letters sl) {
for (int i=0;i<sl.getCount();i++) {
this.lettersLeft.add(sl);
}
}
/**
*Returns the next random letter from the bag.
*/
Letters getNextLetter() {
// shuffle those letters
Collections.shuffle(lettersLeft);
// return a random letter
return lettersLeft.removeFirst();
}
}
字母:
public class Letters {
private char value;
private int count;
private int points;
public Letters(char value, int count, int points) {
this.value = value;
this.count = count;
this.points = points;
}
public char getValue() {
return value;
}
public int getCount() {
return count;
}
public int getPoints() {
return points;
}
答案 0 :(得分:1)
你的意思是?
Collections.shuffle(allLetters);
for(int i=0;i<letterCount;i++)
System.out.println(allLetters[i]);
您的IDE可以为您生成toString方法,您可以简化它。 (或者自己写一个)
