teststringbuffer.java

不错..................是java的源码

import java.lang.*;
class TestStringBuffer {
	public static void main(String[] args) {
		StringBuffer strbuf1= new StringBuffer();
		StringBuffer strbuf2= new StringBuffer("and Java Application");
		strbuf1.append("Hello Java Applet");
		System.out.println(strbuf1.toString());
		strbuf2.insert(0,"Java Applet ");
		System.out.println(strbuf2.toString());
	}
}
