Can'；t在Java中使用DataOutputStream写入整数
我知道这已经被问过很多次了，但是我已经试过了每个人建议的代码，我无法让它在我的系统上工作Can'；t在Java中使用DataOutputStream写入整数,java,macos,file-io,Java,Macos,File Io,我知道这已经被问过很多次了，但是我已经试过了每个人建议的代码，我无法让它在我的系统上工作 public class Heap implements Serializable { public Attribute[] A; // Array of data, has elements name/String, p1/int, n1/int, ig/double private int n = 0; // num elements private int max = 0; /
public class Heap implements Serializable {
public Attribute[] A; // Array of data, has elements name/String, p1/int, n1/int, ig/double
private int n = 0; // num elements
private int max = 0; // Max elements
...
}
public void serialize(Heap hp, String filename) throws IOException {
DataOutputStream dst = new DataOutputStream(new FileOutputStream(filename));
dst.writeInt(hp.heapMax());
dst.writeInt(hp.A.length);
System.out.println("Writing heap max " + hp.heapMax() + " and heap size " + hp.A.length);
for(int i = hp.A.length - 1; i > 0; i--) {
dst.writeInt(hp.A[i].n1);
dst.writeInt(hp.A[i].p1);
dst.writeDouble(hp.A[i].ig);
dst.writeUTF(hp.A[i].name);
}
dst.close();
