import java.math.BigDecimal;

public class Main {
  public static void main(String[] args) {
    BigDecimal decimalA = new BigDecimal("123456789012345");
    BigDecimal decimalB = new BigDecimal("10");

    decimalA = decimalA.pow(2);
    System.out.println("decimalA = " + decimalA);

  }
}

Output:


decimalA = 15241578753238669120562399025
