需要在最后一行的末尾加上分号

Question

I want to put semicolon only at the end of the second line (or the last line) not the first.

Taking three strings in an array: String[] = {"My first string", "My second string", "My last string"};

My current output:

My first string;
My second string;
My last string;

I need output in the form:

My first string My second string My last string;

Answer 1

Try to do something in this way.

String outputString;

for(String str : yourString) {
  outputString = outputString + str;
}

outputString  = outputString  + ";" ;

Other option:

There is the Arrays.toString() method, which will convert an array to a string representation of its contents. Then you can pass that string to System.out.println or whatever you're using to print it.

For example :

  String newString = Arrays.toString(str).replace(",", " ");
  newString = newString.substring(1, newString.length()-1)+";";

Output :

My first string My second string My last string;

Answer 2

Try this:

    for(int i = 0; i < array.length; i++) {
        append(array[i].append((i == array.length-1) ? ";" : ""));
    }

Note that the use of ternary operator will check for the last element of the array. Using this you can control the appending of the a semicolon or a blank

Answer 3

Sure you can, with something like:

class Test {
    public static void main(String[] args) {
        String[] sarr = {"My first string", "My second string", "My last string"};
        String sep = "";
        for (String s: sarr) {
            System.out.print (sep + s);
            sep = " ";
        }
        System.out.println(";");
    }
}

It simply outputs out each string in the array, preceded by a separator (initially an empty string but a single space after the first array element is output).

Then, at the end, it outputs the semicolon and newline:

My first string My second string My last string;

Try below.. it may help

String[] string= {"My first string", "My second string", "My last string"};
string[string.length-1]+=";";
