Java Program to transform alongside worth to String in Java

Right here is our pattern Java program for this information sort conversion. On this program, you’ll study all these three strategies of changing primitive lengthy to String in Java.

/**

public class LongToStringInJava {

    public static void most important(String args[]) {

        // let's first create an extended variable for conversion
        lengthy massive = 3344344323434343L;

        // changing lengthy to String utilizing String concatenation
        // you simply want so as to add quantity with empty String
        // as proven beneath
        String s1 = "" + massive;
        System.out.println("String worth created from lengthy by concatenation : "
                + s1);

        // lengthy to String conversion utilizing Lengthy.toString() methodology
        String s2 = Lengthy.toString(massive);
        System.out.println("String to lengthy utilizing Lengthy.toString() : " + s2);

        // lengthy worth to String utilizing String.valueOf()
        String s3 = String.valueOf(massive);
        System.out.println("String to lengthy utilizing String.valueOf() : " + s3);

    }

}

Output
String worth created from lengthy by concatenation : 3344344323434343
String to lengthy utilizing Lengthy.toString() : 3344344323434343
String to lengthy utilizing String.valueOf() : 3344344323434343

From the output, it is fairly clear that we had been capable of convert the large lengthy worth into String with none drawback. Each Lengthy.toString() and String.valueOf() methodology can also be capable of convert an extended worth with a constructive and unfavourable signal to corresponding String literal as proven beneath :

lengthy longWithPlusSign = +300L;
String str1 = Lengthy.toString(longWithPlusSign);
        
lengthy longWithMinusSign = -333L;
String str2 = String.valueOf(longWithMinusSign);
        
System.out.println("lengthy to String with plus signal : " + str1);
System.out.println("lengthy to String with minus signal : " + str2);

Output
lengthy to String with plus signal : 300
lengthy to String with minus signal : -333

Issues to recollect

1) String.valueOf(lengthy) methodology internally calls Lengthy.toString() methodology.
2) In case you go an indication together with a quantity e.g. constructive or unfavourable signal then transformed String can even comprise that signal however just for unfavourable numbers, not for positives.

That is all about how one can convert lengthy values to String in Java. It is higher to make use of Lengthy.toString() methodology as a result of all different strategies internally name this one solely. If you know the way to transform int to String or double to String, you possibly can comply with the identical steps to transform different information varieties to String in Java as effectively.
