字符转数组，数组转字符串，去出字符串中特定位置的字符

package interview01;

import java.util.Arrays;

public class interview001 {

	public static void main(String[] args) {
		// 面试第一题，对字符串的操作
		int a[]=new int [5];
		System.out.println(a.length);//length 数组的长度
		String name="yangbomingtian";
		System.out.println("字符串长度为"+name.length());//字符串长度
		char a1[];
		char a3=name.charAt(4);
        System.out.println(a3);
		a1=name.toCharArray();//将字符串转换成字符数组
		//a1=Arrays.Sort(a1);;
		String name1=Arrays.toString(a1);//将字符数组转换成字符串
		System.out.println(a1);
		System.out.println(name);
		for(int i=0;i<a1.length;i++) {
			System.out.print(a1[i]+",");
		}
		
		
		System.out.println("name1 size"+name1.length());
		System.out.println("字符串"+name1);
	}
