Java BigInteger intValue() method

The intValue() method of Java BigInteger class is used to convert this BigInteger to a int.This conversion is similar to the narrowing primitive conversion from long to int.

Narrowing Primitive Conversion:

According to The Java Language Specification, it is defined as ifthis BigInteger has too great magnitude to represent as anint, it will return only the lower order 32 bits.

Syntax:

Returns:

This method returns this BigInteger converted to an int.

Note:
This method is specified by intValue in class Number.
When the return value is finite, this conversion can lose information about the precision of the BigInteger value and return a result with the opposite sign.

Example

import java.math.BigInteger;
public class BigIntegerIntValueExample {
public static void main(String[]  args){
// create 4 BigIntegerobjects
BigInteger big1,big2,big3,big4;
// create 4Integerobjects
int int1,int2,int3,int4;
// assign values to big1,big2,big3,big4
big1= new BigInteger("123"); 
big2= new BigInteger("-123"); 
big3= new BigInteger("12345678901");  
big4= new BigInteger("-12345678901");  

// assign intvalue of big1,big2,big3,big4 to int1,int2,int3, int4
 int1=  big1.intValue();
int2=  big2.intValue();
 int3=  big3.intValue();
 int4=  big4.intValue();

String str1= "Result of  intValueoperation on " +big1+"  is  " + int1;
String str2= "Result of  intValueoperation on " +big2+"is" + int2;
String str3= "Result of  intValueoperation on " +  big3 +" is  " +  int3;
String str4= "Result of  intValueoperation on " +  big4 +" is  " +  int4;

// print int1,int2,int3,int4 values
System.out.println(str1);   
System.out.println(str2);
System.out.println(str3);
System.out.println(str4);
}
}

Test it Now

Output:

Result of intValue operation on 123 is 123
Result of intValue operation on -123 is -123
Result of intValue operation on 12345678901 is -539222987
Result of intValue operation on -12345678901 is 539222987
