If one thread invokes this method frequently, other threads that also need frequent synchronized access to the same object will often be blocked. 如果一个线程频繁调用该方法,其他线程若也需要频繁的同步访问同一个对象 通常会被阻塞。 Objects have individuality, and multiple names(in multiple scopes) can be bound to the same object .对象具有个性,多个名称(在多个作用域内)可以绑定到同一个对象 。 Objects have individuality, and multiple names(in multiple scopes) can be bound to the same object .对象是被特化的,多个名字(在多个作用域中)可以绑定同一个对象 。 In such cases, both reference variables will refer to the same object in memory. 在这种情况下,两个引用变量都将引用内存中的同一对象 。 The== compares by reference(does the variables point to the same object ).按引用进行比较(变量是否指向同一对象 )。
The== compares by reference(does the variables point to the same object ).通过引用进行比较(变量是否指向同一对象 )。 In this example, there are two references to the same object . 在这个例子中,有两个对同一个对象 的引用。 The x property in copy1 refers to the same object in memory that x in copy2 refers to, so the strict equality operator returns true.Copy1中的x属性与copy2中的x属性引用了内存中同一个对象 ,因此严格等于(strictequality)运算符返回true. The last example shows that deep_getsizeof() counts references to the same object (the x string) just once, but each reference's pointer is counted.最后一个例子显示了deep_getsizeof()只计算一次同一对象 (x字符串)的引用,但会把每一个引用的指针计算在内。 On reference types, however, Java's== compares reference equality, which means the two variables point to the same object on the JVM's heap. 引用类型:Java的==比较了引用相等性(referenceequality),也就是说比较的是这两个变量是否都指向JVM堆里的同一个对象 。 Variables CAN point to the same object . 多个变量可指向同一个值 。 There may be many references to the same object . 可能有许多对同一对象 的引用。 Return true if x and y refer to the same object . Xisy若返回值为True,则表示x和y引用了同一个对象 。 Two identifiers(name bindings) are bound to the same object in memory, sharing this object: . 即两个标识符(名称绑定)绑定到 内存中的同一个对象 ,共享这个对象:. Objects have individuality, and multiple names(in multiple scopes) can be bound to the same object .对象 具有特性,并且多个名称(在多个作用域中)可以绑定在同一个对象 上。Note that in the last example, p[1] and q really refer to the same object ! 注意最后一个例子,p[1]和q实际上指向同 一个对象!我们在后面会讲到对象 语法。! Note that in the last example, p[1] and q really refer to the same object ! 注意在最后的例子里,p[1]和q确实指向同 一个对象 ! The legal regime applicable to an aerospace object in airspace is indeed different from that applicable to the same object travelling in outer space.适用于空气空间中航空航天物体的法律制度确实不同于适用于在外层空间飞行的同一物体 的法律制度。 Various names can be assigned to the same function object . 各种不同的名称可以绑定到同 一个功能对象 。 Various different names can be bound to the same function object . 各种不同的名称可以绑定到同 一个功能对象 。
