You can typecast or convert a String to Long in Java in many ways. This tutorial will show example codes on how to convert Java Long to String.Performing conversion from long to String is a common scenario when programming with Core Java. A HashMap however, store items in "key/value" pairs, and you can access them by an index of another type (e.g. Feb 18, 2015 Core Java, Examples, Snippet, String comments . Let's see the simple code to convert int to Long in java. Here we have a variable lnum of long data type and we are converting the value of it into an int value which we are storing in the variable inum of int data type. There are mainly two constructors to initialise a Long object-Long(long b): Creates a Long object initialized with the value provided. Here are some quick reference example codes: Convert using Long.toString (long) Java – Convert String to long using Long.parseLong(String) Long.parseLong(String): All the characters in the String must be digits except the first character, which can be a digit or a minus ‘-‘. Next, we assigned int value to a long variable. The int and long data types in Java. The following example shows the usage of java.lang.Long.valueOf() method. s − This is a String containing the long representation to be parsed. Let's see the simple code to convert Long to int in java. field of type long. Exception. String to Long using Long.parseLong() long means numeric datatype. But Integers in Java can only hold 32 bit values which could be insufficient for some tasks. 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.. This method returns the long represented by the argument in decimal. Developed by JavaTpoint. The minimum value of long is -9223372036854775808 and the maximum value of long is 9223372036854775807. An object of Long class can hold a single long value. To learn more, visit … December 1, 2011. We have to pass the long value as argument to toString() method. long l=Long.parseLong ("200"); long l=Long.parseLong ("200"); Let's see the simple example of converting String to long in java.
