BigDecimal plus() method in Java

The java.math.BigDecimal.plus() is an inbuilt method in java that returns a BigDecimal whose value is (+this), and whose scale is this.scale(). This method, which simply returns this BigDecimal is included for symmetry with the unary minus method negate().

Syntax:

public BigDecimal plus()

Parameters: The function does not accepts any parameter.

Return value: This method returns the object value i.e., this.

Below program illustrates the working of the above metioned method:
Program 1:

// Java program to demonstrate the 
// plus() method 
  
import java.math.*; 
  
public class Gfg { 
  
    public static void main(String[] args) 
    { 
  
        // Assign value to b1 
        BigDecimal b1 = new BigDecimal("-45.652"); 
  
        // Assign the result of plus method on 
        // BigDecimal Objects b1 to b2 
        BigDecimal b2 = b1.plus(); 
  
        // Print the value of b2 
        System.out.println("The value of the BigDecimal is " + b2); 
    } 
} 

Output:

The value of the BigDecimal is -45.652

Program 2:

// Java program to demonstrate the 
// plus() method 
  
import java.math.*; 
  
public class gfg { 
  
    public static void main(String[] args) 
    { 
  
        // Assign value to b1 
        BigDecimal b1 = new BigDecimal("7458.3256"); 
  
        // Assign the result of plus method on 
        // BigDecimal Objects b1 to b2 
        BigDecimal b2 = b1.plus(); 
  
        // Print the value of b2 
        System.out.println("The value of the BigDecimal is " + b2); 
    } 
} 

Output:

The value of the BigDecimal is 7458.3256

The java.math.BigDecimal.plus(MathContext mc) is an inbuilt method in java that returns a BigDecimal whose value is (+this), with rounding according to the context settings.

Syntax:

public BigDecimal plus(MathContext mc)

Parameters: This method accepts a single parameter mc which refers to the context of rounding to use i.e., up to what digit the value would be rounded.

Return value: This method returns the value of BigDecimal Object, rounded as necessary. A zero result will have a scale of 0.

Below program illustrates the working of the above metioned method:
Program 1:

// Java program to demonstrate the 
// plus() method 
  
import java.math.*; 
  
public class gfg { 
  
    public static void main(String[] args) 
    { 
  
        BigDecimal b1 = new BigDecimal("-452.325"); 
  
        MathContext m = new MathContext(4); // 4 precision 
  
        // Perform plus on BigDecimal Objects b1 using m 
        BigDecimal b2 = b1.plus(m); 
  
        // Print the value of b2 
        System.out.println("Result of plus is " + b2); 
    } 
} 

Output:

Result of plus is -452.3

Program 2:

// Java program to demonstrate the 
// plus() method 
  
import java.math.*; 
  
public class gfg { 
  
    public static void main(String[] args) 
    { 
  
        BigDecimal b1 = new BigDecimal("-10.325"); 
  
        // 4 precision 
        MathContext m = new MathContext(4);  
  
        // Perform plus on BigDecimal Objects b1 using m 
        BigDecimal b2 = b1.plus(m); 
  
        // Print the value of b2 
        System.out.println("Result of plus is " + b2); 
    } 
} 

Output:

Result of plus is -10.33
