Many methods in StringBuffer class return current object. This allows us to write multiple method calls in one statement like this: s = s.append("It's ").append{10).append(" o'clock."); Based on the J2SDK API S
Example 1 public class StringMethodsTest { @Test public void test1() { String s1 = " Hello, World! "; System.out.println("字符串的长度是:" + s1.length()); //输出 21 System.out.println("字符串中第四个字符是:" + s1.charAt(4)); //输出 e System.out.println("字符串是否为空?"...
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...
