It’s easier to use and works the same everywhere. If you don’t care about the format, consider using Long.toString () to convert a long value into string and Long.parseLong () to convert it back. Here in my above example, I am using Locale.US local. This method can be used to convert String which constitutes of only numbers (or digits) into primitive long data-type However you shouldn’t depend on the default locale, try to specify one instead.Let us move forward and discuss all possible ways to convert String to Long in Java Way 1: Using Long.parseLong(“strValue”) method let’s see one example on this auto-boxing feature at the very end.similarly, Long.valueOf() method returns Long wrapper-type but it can also be used as primitive long data-type.as auto-boxing feature helps to convert primitive data-type to respective wrapper-types.parseLong() method returns primitive long data-type but it can be easily used as Long wrapper-type.Approach : Take a string value and store it in a string variable input1. This method of the Long class converts the String variables into long. Here this method is a wrapper class in Java. This method of the String class returns an array of characters from a given string. String type variable can be converted to long by using parseLong () method, let’s see how it actually works. Hence, there will be no loss in data while converting from int to long.This is called widening typecasting.To learn more, visit Java Typecasting. So, let’s get an up-close look at some of the available methods. In the above example, we have int type variables a and b.Notice the lines, long c a Here, the int type variable is automatically converted into long.It is because long is a higher data type and int is a lower data type.
We show you two ways to convert an IP address to a decimal number.
