如何将char []转换为字符串？

Question

I have a question in this case how to convert char[] to string?(Must explicitly convert the char[] to a String) sorry being a novice programmer i am asking this.

 String str3 = "Dad saw I was Playing";
        System.out.println(str3.toCharArray() + "\n" + str3.toLowerCase() );
        System.out.println(str3.toCharArray());

Output: [C@1034bb5 //this is what I am getting for first str3.tochararray(),how to resolve this?
dad saw i was playing
Dad saw I was Playing

Answer 1

You can use Arrays.toString(char[]) (or create your own method if you prefer a different formatting). Something like,

String str3 = "Dad saw I was Playing";
System.out.println(Arrays.toString(str3.toCharArray()));

Answer 2

System.out.println(str3.toCharArray() + "\\n" + str3.toLowerCase() );

This first calls toString over CharArray which outputs [C@1034bb5 and then append it to the rest of the string and print.

System.out.println(str3.toCharArray()); -- This calls the overridden method in PrintStream class which can interpret char array and print it.

You can explicitly convert your char array to string and print.
