FileChannel fc = new FileInputStream("data.txt").getChannel();
ByteBuffer buff = ByteBuffer.allocate(1024);
fc.read(buff);
buff.flip();?
while (buff.hasRemaining())?这里判断当前位置与限制为之间是否有元素,
System.out.print((char) buff.get());
如果结合API文档,就清晰多了.
1、
public final Buffer flip()
Flips this buffer.The limit is set to the current position and then
the position is set to zero.If the mark is defined then it is
discarded.
2、看英文的意思,判断是否还有数据,有则继续循环
FileChannel fc = new FileInputStream(data.txt).getChannel();ByteBuffer buff = ByteBuffer.allocate(1024);fc.read(buff);buff.flip();?while (buff.hasRemaining())?这里判断当前位置与限制为之间是否有元素,System.out.print((char) buff.ge

已知 AD∥BC,FC∥AE,FC=AE求证AB=CD
已知:AD//BC,FC//AE,求证:AB=CD ................
matlab高手请进看别人的代码看不懂这句:d_NRZ21=[d_NRZ211(2*N_sample*fc+1:N*N_sample*fc),ones(1,N_sample*fc)];fc是载波频率,N_sample是基带码元抽样数,N为码元数.
fc是什么意思
FC是什么意思
fc是什么意思
如图,已知AE/EB=DF/FC=/,求AB/EB,DC/FC,AB/AE,DC/DF的值
FA+FB+FC=0怎么帮这个改成向量表示怎么把FA FB FC用向量表示
A *p= new
A *a2=new
C c = new
Listlist =new ArrayList();
new
