打印没有括号的对象数组

Question

How can i print an array from a 2d without brackets. Basically am adding first the array with the new values to a 2d with :

books=(Object[][]) Arrays.copyOf(row,2);

whereas books is already initialized as 2d array with :

    static Object[][] books=new Object[1][1];

BUT when I try to print the first row from books with :

System.out.println(Arrays.deepToString(books[0])+" ");

it prints me brackets and commas

[asds,asdas,223]

like is suppose to do.

How can i remove those?

Thank you !

Answer 1

您可以使用replaceAll并简单地：

myStr = myStr.replaceAll("\\[|\\]", "");

Answer 2

Try this

    StringBuilder builder = new StringBuilder();

    for (String value : publicArray) {

       builder.append(value +",");

       // or builder.append(value).append(",");
    }

    String text = builder.toString();
    System.out.print(text);

Answer 3

You can try this

String output ;
    for(String s: books[0]){
      output = output +s+ ",";
    }
output = output.substring(0, output.length()-1);
System.out.print(output);
