charatstring.java

一些基本的java程序源代码

package charatstring;

public class CharAtString {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		String text="One's left brain has nothing right.\n"
			+"One's right brain has nothing left.\n";
			
			System.out.println("字符串内容：");
		for(int i=0;i<text.length();i++)
			System.out.print(text.charAt(i));
		
		System.out.println("\n第一个left:"+text.indexOf("left"));
		System.out.println("\n最后一个left:"+text.lastIndexOf("left"));
		char[] charArr=text.toCharArray();
		System.out.println("\n字符Array内容:");
		for(int i=0;i<charArr.length;i++)
			System.out.print(charArr[i]);

	}
