Java Convert long to BigDecimal

In this Java core tutorial we learn how to convert a long value to a java.math.BigDecimal object in Java programming language.

How to convert long to BigDecimal in Java

In Java, with a given long value we can use the BigDecimal.valueOf(long val) static method to instantiate a new BigDecimal object from a long value as the following example Java code.

ConvertLongToBigDecimalExample1.java 

import java.math.BigDecimal;

public class ConvertLongToBigDecimalExample1 {
    public static void main(String... args) {
        long longValue = 111222333;

        // Convert long value to BigDecimal object
        BigDecimal bigDecimalValue = BigDecimal.valueOf(longValue);

        System.out.println("Long value: " + longValue);
        System.out.println("BigDecimal value: " + bigDecimalValue);
    }
}
The output as below. 
Long value: 111222333
BigDecimal value: 111222333

We can also use the BigDecimal(long val) constructor to create a new instance of BigDecimal from a given long value as the Java code below.

ConvertLongToBigDecimalExample2.java 

import java.math.BigDecimal;

public class ConvertLongToBigDecimalExample2 {
    public static void main(String... args) {
        long longValue = 900800700;

        // Convert long value to BigDecimal object
        BigDecimal bigDecimalValue = new BigDecimal(longValue);

        System.out.println("Long value: " + longValue);
        System.out.println("BigDecimal value: " + bigDecimalValue);
    }
}
The output as below. 
Long value: 900800700
BigDecimal value: 900800700
