stringbufferindexofdemo.java

JAVA编程思想源代码 值得一下 很难找的

package chapter8;

public class StringBufferIndexOfDemo {

	public static void main(String[] args) {

		StringBuffer sbf = new StringBuffer(50);
		sbf.append("i am a stringbuffer");
		for(int i=0;i<sbf.length();i++)
		{
			System.out.println("char["+i+"] "+sbf.charAt(i));
		}
		int x1 = sbf.indexOf("f");
		System.out.println("x1 = " + x1);
		int y1 = sbf.lastIndexOf("a");
		System.out.println("y1 = " + y1);

	}
