我启动时会给出错误,类名是AQueueClass 有帮助吗?
package `com.thekyle.hi;`
class QDemo {
// a queue class for characters
char q[]; // this array holds the queue
int putloc, getloc; // the put and get indices
QDemo(int size) {
q = new char[size + 1];
putloc = getloc = 0;
}// put a character into the queue
void put(char ch) {
if (putloc == q.length - 1) {
System.out.println(" - Queue is full silly- ");
return;
}
putloc++;
q[putloc] = ch;
}
char get() {// gets a character from the queue
if (getloc == putloc) {
System.out.println(" Queue is empty");
return (char) 0;
}
getloc++;
return q[getloc];
}
}
class AQueueClass {
public static void main(String args[]) {
QDemo bigQ = new QDemo(100);
QDemo smallQ = new QDemo(4);
char ch;
int i;
System.out.println("Using bigQ to store the alphabet");
for (i = 0; i < 26; i++) {
bigQ.put((char) ('A' + i));
// retrieve and display elements from bigQ
System.out.println("Contents of bigQ: ");
for (i = 0; i < 26; i++) {
ch = bigQ.get();
if (ch != (char) 0)
System.out.print(ch);
}
System.out.println("\n");
System.out.println("Using small q to generate errors");
for (i = 0; i < 5; i++) {
System.out.print("Attemting to store " + (char) ('Z' - i));
smallQ.put((char)('Z' - i));
System.out.println();
}
System.out.println();
System.out.println("Contents of smallQ: ");
for (i = 0; i < 5; i++) {
ch = smallQ.get();
if( ch != (char) 0 ) System.out.print(ch);
}
}
}
}
如果是类路径问题,我在哪里可以找到类路径?因为它说我需要更多细节,所以这里有一些填充物。

以什么名称保存您的java文件。如果你的java文件中有两个类,那么尝试将包含 main()方法的类作为公共类。

尝试使用名称 AQueueClass 保存文件,并在 AQueueClass 类前添加公开关键字。编译它并再次运行它。我认为它会奏效。
