bigInteger to int code example

Example 1: java long to int

public class LongToIntExample2{
      
    	public static void main(String args[]){
          
        	Long l= new Long(10);
        	int i=l.intValue();
        	System.out.println(i);
    	
        }
    }

Example 2: java int to biginteger

// Primitive int
int myInt = 10
BigInteger bigInt = BigInteger.valueOf(myInt);
// Integer object
Integer integer = Integer.valueOf(myInt);
BigInteger bigInt = BigInteger.valueOf(myInteger.intValue());
bigInt = BigInteger.valueOf(myInteger);		// works too

Example 3: java long to integer

// auto-unboxing does not go from Long to int directly, so
Integer i = (int) (long) theLong;
