Description

The java.math.BigInteger.toString() returns the decimal String representation of this BigInteger. The digit-to-character mapping provided by Character.forDigit is used, and a minus sign is prepended if appropriate.

This representation is compatible with the (String) constructor, and allows for String concatenation with Java's + operator.

Declaration

Following is the declaration for java.math.BigInteger.toString() method.

public String toString()

Overrides

toString in class Object.

Parameters

NA

Return Value

This method returns the decimal String representation of this BigInteger.

Exception

NA

Example

The following example shows the usage of math.BigInteger.toString() method.

package com.tutorialspoint;

import java.math.*;

public class BigIntegerDemo {

   public static void main(String[] args) {

      // create 2 BigInteger objects
      BigInteger bi1, bi2;

      // create 2 String objects
      String s1, s2;

      bi1 = new BigInteger("1234");
      bi2 = new BigInteger("-1234");

      // assign String value of bi1, bi2 to s1, s2
      s1 = bi1.toString();
      s2 = bi2.toString();

      String str1 = "String value of " + bi1 + " is " +s1;
      String str2 = "String value of " + bi2 + " is " +s2;

      // print s1, s2 values
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

Let us compile and run the above program, this will produce the following result −

String value of 1234 is 1234
String value of -1234 is -1234
