Java long to String

To convert a long value to a String in Java, you can use the Long.toString() method. Here’s an example:

long num = 123456789;
String str = Long.toString(num);
System.out.println(str); // prints "123456789"

Alternatively, you can also use the String.valueOf() method to convert a long to a String:

long num = 123456789;
String str = String.valueOf(num);
System.out.println(str); // prints "123456789"

Both of these methods will convert a long value to a String representation.

1) String.valueOf():

String.valueOf() is a method in Java that returns a String representation of the given argument. It is an overloaded method, which means it can take different types of arguments and return their respective String representations.

Here are a few examples of how String.valueOf() can be used:

// Convert an int to a String
int num1 = 123;
String str1 = String.valueOf(num1); // str1 = "123"

// Convert a double to a String
double num2 = 3.14;
String str2 = String.valueOf(num2); // str2 = "3.14"

// Convert a boolean to a String
boolean flag = true;
String str3 = String.valueOf(flag); // str3 = "true"

In all of these examples, String.valueOf() is used to convert a value to its String representation. Note that for primitive types like int, double, and boolean, the method returns the equivalent String representation of the value. For objects, String.valueOf() calls the object’s toString() method to get its String representation.

Java long to String Example using String.valueOf():

Sure, here’s an example of how to convert a long value to a String using String.valueOf() method:

long num = 123456789;
String str = String.valueOf(num);
System.out.println(str); // prints "123456789"

In this example, the long value 123456789 is converted to a String using String.valueOf() method and assigned to the str variable. The println() method is then used to print the str variable, which outputs the String representation of the long value as "123456789".

2) Long.toString():

Long.toString() is a method in Java that returns a String representation of a long value. It is a static method of the Long class, which means it can be called directly on the class without needing to create an instance of it.

Here’s an example of how to use Long.toString() to convert a long value to a String:

long num = 123456789;
String str = Long.toString(num);
System.out.println(str); // prints "123456789"

In this example, the long value 123456789 is converted to a String using Long.toString() method and assigned to the str variable. The println() method is then used to print the str variable, which outputs the String representation of the long value as "123456789".

Long.toString() also has an overloaded version that allows you to specify the radix (base) of the resulting String. For example, if you want to convert a long value to its hexadecimal representation, you can call Long.toString(num, 16):

long num = 255;
String hex = Long.toString(num, 16);
System.out.println(hex); // prints "ff"

In this example, the long value 255 is converted to its hexadecimal representation using Long.toString(num, 16) method and assigned to the hex variable. The println() method is then used to print the hex variable, which outputs the String representation of the long value in hexadecimal as "ff".

Java long to String Example using Long.toString():

Here’s an example of how to convert a long value to a String using Long.toString() method:

long num = 123456789;
String str = Long.toString(num);
System.out.println(str); // prints "123456789"

If you want to convert a long value to its hexadecimal representation, you can call Long.toString() with a radix (base) of 16:

long num = 255;
String hex = Long.toString(num, 16);
System.out.println(hex); // prints "ff"
