在Java中，成员变量的初始化有以下几种方式：

public class MyClass {
    private int num = 10;
}

public class MyClass {
    private int num;
    
    public MyClass() {
        num = 10;
    }
}

public class MyClass {
    private int num;
    
    {
        num = 10;
    }
}

public class MyClass {
    private static int num;
    
    static {
        num = 10;
    }
}

public class MyClass {
    private int num;
    
    public void setNum(int value) {
        num = value;
    }
}
