In Java, you can convert a BigDecimal to an int by using the intValue() method, which converts the BigDecimal to a value of type int.

Here is an example code:

import java.math.BigDecimal;

public class BigDecimalToIntExample {
    public static void main(String[] args) {
        BigDecimal bigDecimal = new BigDecimal("1234.56");
        
        int intValue = bigDecimal.intValue();
        
        System.out.println("BigDecimal转换为int的值为: " + intValue);
    }
}

The output result is:

BigDecimal转换为int的值为: 1234

Please note that when using the intValue() method to convert a BigDecimal to an int type, the decimal part will be directly removed, leaving only the integer part. If you need to round up or perform other rounding operations, you can first set the precision using the setScale() method on the BigDecimal, and then proceed with the conversion. For example:

import java.math.BigDecimal;
import java.math.RoundingMode;

public class BigDecimalToIntExample {
    public static void main(String[] args) {
        BigDecimal bigDecimal = new BigDecimal("1234.56");
        
        BigDecimal roundedValue = bigDecimal.setScale(0, RoundingMode.HALF_UP);
        
        int intValue = roundedValue.intValue();
        
        System.out.println("BigDecimal转换为int的值为: " + intValue);
    }
}

The output result is:

BigDecimal转换为int的值为: 1235
