temp.equals("J")

As an AI language model, I cannot determine the context of this statement. It seems to be a comparison of the value of the variable "temp" with the string "J". The result of this comparison would be a boolean value (either true or false) depending on whether the two values are equal or not.

private HashMap<String,Vector<String>> graphs =new HashMap<String,Vector<String>>(); public Graphs() { } public Graphs(HashMap<String, Vector<String>> graphs) { this.graphs = graphs; } public void creatGraphs(Vector<String> userTemp/* allusers */, Vector<String> linksTemp/* links */) { for(int i=0;i<userTemp.size();i++) { Vector<String> vecLinksTemp=new Vector<String>();//创建当前user能够激活的links容器 for(int j=0;j<linksTemp.size();j++) { if(((String)linksTemp.get(j)).split(" ")[0].equals(userTemp.get(i)))//判断与user的匹配的links vecLinksTemp.add(((String)linksTemp.get(j))); } graphs.put((String)userTemp.get(i),vecLinksTemp); } } public void setGraphs(HashMap<String, Vector<String>> graphs) { this.graphs = graphs; } public HashMap<String, Vector<String>> getGraphs() { return graphs; }

这段 Java 代码定义了一个名为 Graphs 的类，其中包含了一个名为 graphs 的 HashMap 成员变量，用于存储字符串和字符串向量之间的映射关系。

该类有三个方法：

1. 无参构造方法 public Graphs()。

2. 有参构造方法 public Graphs(HashMap<String, Vector<String>> graphs)，用于初始化 graphs 成员变量。

3. public void creatGraphs(Vector<String> userTemp, Vector<String> linksTemp)，用于创建图形对象，并将其添加到 HashMap 中。该方法通过遍历 userTemp 和 linksTemp 两个向量，根据给定的条件，将 linksTemp 中的元素添加到 vecLinksTemp 中，最后将 vecLinksTemp 添加到 graphs 中。

该类还有两个访问器方法：

1. public void setGraphs(HashMap<String, Vector<String>> graphs)，用于设置 graphs 成员变量的值。

2. public HashMap<String, Vector<String>> getGraphs()，用于获取 graphs 成员变量的值。

总之，这段代码实现了一个简单的图形数据结构，并提供了一些基本的操作方法。

把下面这段js代码转换为java代码 function getMatchList(peopleList,round_num) { while ((peopleList.length*round_num)%4!=0) { round_num++; } let matchListPoor = getTempMatchList(peopleList,round_num); let all_round = matchListPoor.length/2; let res = []; let rivalry = []; let round = 0; while (matchListPoor.length>0) { let per = matchListPoor[0]; matchListPoor.splice(0,1); if(rivalry.length==0){ rivalry.push(per); round = 1; }else if(!rivalry[0].includes(per[0])&&!rivalry[0].includes(per[1])){ rivalry.push(per); }else{ matchListPoor.push(per); round = 2; } if(rivalry.length==2){ res.push(rivalry); rivalry = []; } if(matchListPoor.length==1&&round == 2){ matchListPoor = [...matchListPoor,...rivalry]; for (let j = 0; j < res.length; j++) { if(!res[j][0].includes(matchListPoor[0][0])&&!res[j][0].includes(matchListPoor[0][1])){ let temp = res[j][1]; res[j][1] = matchListPoor[0]; matchListPoor[0] = temp; if(!matchListPoor[0].includes(matchListPoor[1][0])&&!matchListPoor[0].includes(matchListPoor[1][1])){ res.push(matchListPoor); break; } } } } if(res.length==all_round){ break; } } return res; }

下面是将给定的 JavaScript 代码翻译成 Java 代码的示例：

public static List<List<String[]>> getMatchList(List<String[]> peopleList, int round_num) {
    while ((peopleList.size() * round_num) % 4 != 0) {
        round_num++;
    }
    List<String[][]> matchListPoor = getTempMatchList(peopleList, round_num);
    int all_round = matchListPoor.size() / 2;
    List<List<String[]>> res = new ArrayList<>();
    List<String[][]> rivalry = new ArrayList<>();
    int round = 0;
    while (matchListPoor.size() > 0) {
        String[][] per = matchListPoor.get(0);
        matchListPoor.remove(0);
        if (rivalry.size() == 0) {
            rivalry.add(per);
            round = 1;
        } else if (!contains(rivalry.get(0), per[0]) && !contains(rivalry.get(0), per[1])) {
            rivalry.add(per);
        } else {
            matchListPoor.add(per);
            round = 2;
        }
        if (rivalry.size() == 2) {
            res.add(Arrays.asList(rivalry.get(0), rivalry.get(1)));
            rivalry.clear();
        }
        if (matchListPoor.size() == 1 && round == 2) {
            matchListPoor.addAll(rivalry);
            for (int j = 0; j < res.size(); j++) {
                if (!contains(res.get(j).get(0), matchListPoor.get(0)[0])
                        && !contains(res.get(j).get(0), matchListPoor.get(0)[1])) {
                    String[][] temp = res.get(j).get(1);
                    res.get(j).set(1, matchListPoor.get(0));
                    matchListPoor.set(0, temp);
                    if (!contains(matchListPoor.get(0), matchListPoor.get(1)[0])
                            && !contains(matchListPoor.get(0), matchListPoor.get(1)[1])) {
                        res.add(Arrays.asList(matchListPoor.get(0), matchListPoor.get(1)));
                        break;
                    }
                }
            }
        }
        if (res.size() == all_round) {
            break;
        }
    }
    return res;
}

private static boolean contains(String[][] arr, String str) {
    return Arrays.stream(arr).flatMap(Arrays::stream).anyMatch(s -> s.equals(str));
}

private static List<String[][]> getTempMatchList(List<String[]> peopleList, int round_num) {
    List<String[][]> tempMatchList = new ArrayList<>();
    for (int i = 0; i < round_num; i++) {
        String[][] matchList = new String[peopleList.size() / 2][2];
        for (int j = 0; j < peopleList.size() / 2; j++) {
            matchList[j] = new String[]{peopleList.get(j)[0], peopleList.get(peopleList.size() - 1 - j)[0]};
        }
        peopleList.remove(0);
        peopleList.remove(peopleList.size() - 1);
        tempMatchList.add(matchList);
    }
    return tempMatchList;
}

需要注意的是，Java 中没有类似 JavaScript 中的 `splice()` 方法，因此需要使用 `remove()` 方法和 `addAll()` 方法代替。另外，在 Java 中，数组不能直接作为列表的元素，因此需要使用二维字符串数组 `String[][]` 代替。
