We can use StringBuilder and StringBuffer append function to convert long to string. String str = DecimalFormat.getNumberInstance().format(l) String str = new Long(l).toString() // str is '12345' deprecated from Java 9, use valueOf for better performance Java Interviews can give a hard time to programmers, such is the severity of the process. Long constructor with long argument has been deprecated in Java 9, but you should know it. VBA Convert Integer To String With Leading Zeros. String str = String.valueOf(l) // str is '12345' Let’s look into other ways to convert long to string too. So the string is always being returned in decimal format. We can write long in other formats too such as Octal and Hexadecimal, let’s see what happens when we convert long to string in those scenarios.

I was in the process of creating a simple calculator in java using Swing. Java example to convert int to String value This example shows how to use above both methods i.e. We can use Long class toString method to get the string representation of long in decimal points. Integer.valueOf () Using code () Using constructor new Integer (String) Conclusion. This is the easiest way to convert long to string in java. However java supports autoboxing, so they both can be used interchangeably in most of the cases. Note that long is a primitive data type whereas Long is an Object. Let’s look at different code snippets for java long to string conversion.

YASH PAL FebruIn this HackerRank Java Int to String problem in java programming language You are given an integer n, you have to convert it into a string. The following code demonstrates the methods listed above.Today we will see different ways to convert long to string in java. We should use parseInt () to convert a string to an int primitive or use valueOf () to convert it to an Integer object.

static Short valueOf(String s, int radix) returns a Short object holding the value extracted from the specified String when parsed with the radix given by the second argument.

static Short valueOf(String s) returns a Short object holding the value given by the specified String.

static Short valueOf(short s) returns a Short instance representing the specified short value.

static short parseShort(String s, int radix) parses the string argument as a signed short in the radix specified by the second argument.

All characters in the string argument must be.

static short parseShort(String s) parses the string argument as a signed decimal short. Java parseInt method First solution The parseInt method parses the given string as a signed decimal integer.

It is a static method that takes an int primitive argument and returns an Integer object. It passes the method reference as a parameter to the generic function. NumberUtils::toInt // (provided by Apache Commons Lang) Following is a generic version of the above program. Here, we used valueOf () method of the Integer class. For converting a string to an Integer, we can pass any one of the following method references to the map () method: Integer::parseInt. It returns a string that is equivalent to the char sequence represented by StringBuilder object. Convert Int to Integer Using the Integer.valueOf () Method in Java This is another that we can use to convert an int to an Integer in Java. Short class has the following methods we can use to convert a string to a short type value. public string toString(): Returns a String representation of the StringBuilder sequence.
