z这个代表什么意思??
..
System.out.print(Thread.currentThread());
accounts[from] -= amount;
System.out.printf("%10.2f from %d to %d", amount, from, to);
accounts[to] += amount;
System.out.printf("Total Balance: %10.2f%n", getTotalBalance());
sufficientFunds.signalAll();
.
.
这两句中间 %10.2f%n %10.2f 是什么意思?
懵懵懂懂，看千遍而不会；设身处地，试一下就成功！
