我正在尝试从文件中读取一组数字然后隔离第一行之间的行(这让我们知道需要处理多少行,在本例中为5)和第七行(请注意,这只是一个示例,行的范围可能会发生变化),以便我可以填充格式为(0 1 98,0 2 5,...,4 3 15)的列表。现在我的代码设法将(0 1 98,0 2 5,0 3 16,0 4 16)添加到列表中但不添加其余部分。我不确定我做错了什么。任何帮助将非常感激。
示例输入:
5
0 1 98 2 5 3 16 4 16
1 0 13 2 47 3 3 4 40
2 0 71 1 51 3 43 4 30
3 0 20 1 94 4 46
4 0 1 1 10 2 28 3 15
2
2 3
2
0 1
public static void t() {
List<String> L = new ArrayList();
try {
BufferedReader f = new BufferedReader(new FileReader("graph.txt"));
String s = f.readLine();
int nodes = Integer.parseInt(s);
int c = -1;
int c1 = 2;
int c2 = 3;
for (int i = 0; i < nodes; i++) {
s = f.readLine();
String z [] = s.split(" ");
String start = z[0];
for (int j = 0; j < z.length; j++) {
int t = c+c1;
int t2 = c+c2;
if (t >= z.length) {
break;
}
String des = z[t];
if (t2 >= z.length+1) {
break;
}
String weight = z[t2];
L.add(start + " " + des + " " + weight);
c1+=2;
c2+=2;
}
}
for (int i = 0; i < L.size(); i++) {
System.out.println(L.get(i));
}
} catch (Exception ex) {
System.out.println(ex);
}
}
答案 0 :(得分:1)
您只需要在外部循环中重置C
个变量。
for (int i = 0; i < nodes; i++) {
s = f.readLine();
String z [] = s.split(" ");
String start = z[0];
// Declare the variables here, otherwise code is the same
int c = -1;
int c1 = 2;
int c2 = 3;
for (int j = 0; j < z.length; j++) {
int t = c+c1;
int t2 = c+c2;
if (t >= z.length) {
break;
}
String des = z[t];
if (t2 >= z.length+1) {
break;
}
String weight = z[t2];
L.add(start + " " + des + " " + weight);
c1+=2;
c2+=2;
}
}
