代码输出错误，我不理解。对于您的第一个问题，即使是错误的地方，也有答案，只需替换您的
// ...
for (int i = 0; i < line; i++) {
int sourceNode = input.nextInt();
System.out.println("SourceNode: " + sourceNode);
int distNode = input.nextInt();
System.out.println("DistNode: " + distNode );
input.nextLine();
// you will get same response with following code instead all your if's:
for (int j = 0; j < primaryArray[distNode].length; j++) {
if (primaryArray[distNode][j] == sourceNode)
dualPass[sourceNode] = true;
}
if (dualPass[sourceNode] != true) {
primaryArray[sourceNode][number[sourceNode]] = distNode;
number[sourceNode]++;
}
dualPass[sourceNode] = false;
// end of code change
}
// ...
只有当我们获得更多信息时，才能回答您的第二个答案，我还不知道您的代码应该做什么。1。从遵循命名约定开始。java中的变量名以小写字母开头。除此之外，还有一个地方可以让代码更清晰，而不是StackOverflow。2.我不知道你在第二点中问了什么，也不知道程序应该做什么。输出必须是每个成员的第二个-什么？我对这里输入/输出之间的关系感到非常困惑。
// ...
for (int i = 0; i < line; i++) {
int sourceNode = input.nextInt();
System.out.println("SourceNode: " + sourceNode);
int distNode = input.nextInt();
System.out.println("DistNode: " + distNode );
input.nextLine();
// you will get same response with following code instead all your if's:
