java字符数组与字符串相互转换

1.字符串转化为字符数组

public class Hello {  
    public static void main(String args[]){
        Scanner input = new Scanner(System.in);
       String str="abc";
       char[] c=str.toCharArray();
       for(int i=0;i<c.length;i++)
       System.out.print(c[i]);
    }    
}

2.字符数组转化为字符串

public class Hello {
	public static void main(String args[]){ 
       char[] cc={'a','b','c'};
       String s=String.valueOf(cc);
     System.out.println(s);
	}	
}
