# 2 ways to Convert String to BigDecimal in Java with Examples

In this tutorial, I will be sharing how to convert String to BigDecimal in java with examples. There are two ways to achieve it.

1. Using Constructor of Big Decimal class [Recommended]

2. Using BigDecimal.valueOf() method

## 1. Using Constructor of Big Decimal

This is the easiest way to convert String to BigDecimal in java. Just use BigDecimal(String) constructor.

`BigDecimal obj = new BigDecimal(String);`

The above line will do the job. You can find the example below:

```import java.math.*;
public class JavaHungry {
public static void main(String args[])
{
String str = "123.45";
// Using BigDecimal(String) constructor
BigDecimal num = new BigDecimal(str);
// Printing BigDecimal value
System.out.println("Converted String to BigDecimal : " + num);
}
}
```

Output:
Converted String to BigDecimal : 123.45

Note: String passed in a constructor should be a valid number otherwise NumberFormatException will be thrown.

## 2. Using BigDecimal.valueOf() method

Convert String to BigDecimal by using BigDecimal.valueOf(double) method.
It is a two-step process. The first step is to convert the String to Double. The second step is to convert Double to BigDecimal, using BigDecimal.valueOf(double) method. As shown in the example below:

```import java.math.*;
public class JavaHungry {
public static void main(String args[])
{
String str = "123.45";
// Converting String to Double
Double obj = new Double(str);
// Converting Double to BigDecimal
BigDecimal num = BigDecimal.valueOf(obj);
// Printing BigDecimal value
System.out.println("Converted String to BigDecimal: " + num);
}
}
```

Output:
Converted String to BigDecimal: 123.45

Note: BigDecimal.valueOf(double) is a static method. You do not need to create a BigDecimal object to access it.

That's all for the day. Please mention in comments in case you have any questions related to convert String to BigDecimal in java with examples.
