How to enter quotes in a Java string?

问题

I want to initialize a String in Java, but that string needs to include quotes; for example: \"ROM\". I tried doing:

String value = \" \"ROM\" \";

but that doesn\'t work. How can I include \"s within a string?

回答1:

In Java, you can escape quotes with \:

String value = " \"ROM\" ";

回答2:

In reference to your comment after Ian Henry's answer, I'm not quite 100% sure I understand what you are asking.

If it is about getting double quote marks added into a string, you can concatenate the double quotes into your string, for example:

String theFirst = "Java Programming";
String ROM = "\"" + theFirst + "\"";

Or, if you want to do it with one String variable, it would be:

String ROM = "Java Programming";
ROM = "\"" + ROM + "\"";

Of course, this actually replaces the original ROM, since Java Strings are immutable.

If you are wanting to do something like turn the variable name into a String, you can't do that in Java, AFAIK.

回答3:

Not sure what language you're using (you didn't specify), but you should be able to "escape" the quotation mark character with a backslash: "\"ROM\""

回答4:

Just escape the quotes:

String value = "\"ROM\"";

回答5:

\ = \\

" = \"

new line = \r\n OR \n\r OR \n (depends on OS) bun usualy \n enough.

taabulator = \t

回答6:

In Java, you can use char value with ":

char quotes ='"';

String strVar=quotes+"ROM"+quotes;

回答7:

Look into this one ... call from anywhere you want.

public String setdoubleQuote(String myText) {
    String quoteText = "";
    if (!myText.isEmpty()) {
        quoteText = "\"" + myText + "\"";
    }
    return quoteText;
}

apply double quotes to non empty dynamic string. Hope this is helpful.

Here is full java example:-

public class QuoteInJava {     

public static void main (String args[])
    {
            System.out.println ("If you need to 'quote' in Java");
            System.out.println ("you can use single \' or double \" quote");
    }
}

Here is Out PUT:-

If you need to 'quote' in Java
you can use single ' or double " quote

回答9:

suppose ROM is string variable which equals "strval" you can simply do

String value= " \" "+ROM+" \" ";

it will be stored as

value= " "strval" ";
