2. 实现值类型的Equals: Override the virtualObject.Equals(Object) method. In most cases, your implementation of bool Equals( object obj ) should just call into the type-specific Equals method that is the implementation of the System.IEquatable<T> interface. (See step 2.) (重写Equals方法或者...
1、直接赋值Stringstr="zhangsan"; 2、通过构造方法String(byte[]bytes,intoffset,intlength)String(char[]bytes,intoffset,intcount) 代码实现 publicclassDemo2{/*** String 类的定义方式* 1、直接赋值 String str = "zhangsan";* 2、通过构造方法 String(byte[] bytes, int offset, int length)* String(...
The following example demonstrates theEqualsmethod. C# // Sample for String.Equals(Object)// String.Equals(String)// String.Equals(String, String)usingSystem;usingSystem.Text;classSample1{publicstaticvoidMain(){ StringBuilder sb =newStringBuilder("abcd"); String str1 ="abcd"; String str2 =null...
The following code example uses three versions of theEqualsmethod to determine whether aStringobject and aStringBuilderobject are equal. The results are affected by the choice of culture, whether case is ignored, and whether an ordinal comparison is performed. ...

( + ), and for conversion of other objects to strings. String concatenation is implemented through theStringBuilder(orStringBuffer) class and itsappendmethod. String conversions are implemented through the methodtoString, defined byObjectand inherited by all classes in Java. For additional information ...
23.解释内存中的栈(stack)、堆(heap)和方法区(method area)的用法。 通常我们定义一个基本数据类型的变量,一个对象的引用,还有就是函数调用的现场保存都使用JVM中的栈空间;而通过new关键字和构造器创建的对象则放在堆空间,堆是垃圾收集器管理的主要区域,由于现在的垃圾收集器都采用分代收集算法,所以堆空间还可以细...
