All string literals in Java programs, such as "abc", are implemented as instances of this class. Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings. Because String objects are immutable they can be shared. For example: String ...
* string literals in Java programs, such as "abc", are * implemented as instances of this class. * * Strings are constant; their values cannot be changed after they * are created. String类存在于java.lang包中。上述大概意思:String是一个字符串,String的字面量也是String的一个实例。String它的...
* The {@code String} class represents character strings. All string literals in Java programs, such as {@code "abc"}, are * implemented as instances of this class. * {@code String}类表示字符串。Java程序中的所有字符串文本,例如{@code“abc”},都是作为这个类的实例实现的。

A String in Java is actually an object, which contain methods that can perform certain operations on strings. For example, the length of a string can be found with the length() method: Example String txt = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; System.out.println("The length of the txt string is...
