LearnThreadSync.java 代码

package ThreadSync;

public class LearnThreadSync {
    public static void main(String[] args) {
        BankAccount account=new BankAccount();
        Thread husband=new BankThread(account);
        Thread wife=new BankThread(account);
        husband.start();
        wife.start();
        
    }

}

BankAccount.java 代码

package ThreadSync;

public class BankAccount {

    private double balance=1000;
    public boolean deposit(double newAdd){
        if(newAdd<=0){
            return false;
        }else{
            synchronized (this) {
                System.out.println("当前余额为"+balance);
                try {
                    Thread.sleep(5);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                balance=balance+newAdd;
                System.out.println("您的余额为"+balance);
            }
            return true;
        }
    }
}

BankThread.java 代码

package ThreadSync;

public class BankThread extends Thread {
    private BankAccount bankAccount;
    public BankThread(BankAccount account){
        bankAccount=account;
