怎么重写toString()才能把数组打印出来

[abclihongzhi]

public class MyClass {
	public static void main(String[] args) throws Exception {
		String s = "'c':'d':'e':'a'";
		String[] sg = s.split(":");
		System.out.println(sg);
		
		
		
		String str = "wwwwwwwwww";

		byte[] strBytes = new byte[str.length()];

		strBytes = str.getBytes();
		System.out.println(strBytes);
	}
}

额，可以直接用Arrays.toString(strBytes)

想多了，
数组的toString()方法还真不是能直接重写的，

结果是：
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
不对啊，没把w打印出来。

哈哈 写个山寨的！

public class ArrayTest {
    public static void main(String[] args) {
    	ArrayString astr;
    	String s = "'c':'d':'e':'a'";
        String[] sg = s.split(":");
        astr = new ArrayString(sg);
        System.out.println(astr);

        }

  }

class ArrayString {
	
	private String[] str;

    public ArrayString(String[] str) {
       this.str = str;
        // System.out.println(x);
        // System.out.println(y);
        // System.out.println(z);
    }
    
    public String toString(){
    	String returnString = "";
    	for(String strTemp:str){
    		returnString += strTemp;
    	}
    	return returnString;
    	
    }
}

写个工具类，接受一个数组的参数，然后迭代数组的每个元素，然后按特定格式输出。

import java.util.Arrays;

public class MyClass {
    public static void main(String[] args) throws Exception {
        String s = "'c':'d':'e':'a'";
        String[] sg = s.split(":");
        System.out.println(Arrays.toString(sg));
        
        String str = "wwwwwwwwww";
        byte[] strBytes = new byte[str.length()];
        strBytes = str.getBytes();
        System.out.println(Arrays.toString(strBytes));
    }
}

输出：
['c', 'd', 'e', 'a']
[119, 119, 119, 119, 119, 119, 119, 119, 119, 119]
