java.lang.StringBuffer的append(char c)方法将char参数的字符串表示形式附加到此序列。参数将附加到此序列的内容中。该序列的长度增加1。
import java.lang.*; public class StringBufferDemo { public static void main(String[] args) { StringBuffer buff = new StringBuffer("tuts "); System.out.println("buffer = " + buff); //将char参数作为字符串追加到字符串缓冲区。 buff.append('A'); //之后打印字符串缓冲区 System.out.println("After append = " + buff); buff = new StringBuffer("abcd "); System.out.println("buffer = " + buff); //将char参数作为字符串追加到字符串缓冲区。 buff.append('!'); //之后打印字符串缓冲区 System.out.println("After append = " + buff); } }
输出结果
buffer = tuts After append = tuts A buffer = abcd After append = abcd !
