A thread-safe, mutable sequence of characters. A string buffer is like aString, but can be modified.At any point in time it contains some particular sequence of characters, but the length and content of the sequence can be changed through certain method calls. String buffers are safe for use...
String buffers 支持可变String. 因为String是不可变的, 所以它们可以被共享. 例如: String str = "abc"; 等价于 char data[] = {'a', 'b', 'c'}; String str = new String(data); 源码中提供的其他使用String的例子: System.out.println("abc");...
At any point in time it contains some particular sequence of characters, but the length and content of the sequence can be changed through certain method calls. String buffers are safe for use by multiple threads. The methods are synchronized where necessary so that all the operations on any ...
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 str = "abc"; is equivalent to: char data[] = {'a', 'b', 'c'}; String str = new String(...
String buffers support mutable strings. Because String objects are immutable they can be shared. For example: String str = "abc"; is equivalent to: char data[] = {'a', 'b', 'c'};String str = new String(data); Here are some more examples of how strings can be used: System.out....

String buffers are safe for use by multiple threads. The methods are synchronized where necessary so that all the operations on any particular instance behave as if they occur in some serial order that is consistent with the order of the method calls made by each of the individual threads invo...
String buffers use an exponential growth strategy that makes appending to a string a constant time operation when averaged over many append operations. Bridging Between String and NSString Any String instance can be bridged to NSString using the type-cast operator (as), and any String instance ...
