3. Check equality in List of objects To compare two lists of objects in Java, you can use either List.equals(…) or Objects.equals(…) methods, as discussed above. However, you would also need to override equals and hashCode methods for that object in Java. The following program demonstra...

”0.00”.equals(BigDecimal.ZERO) returns false and equals method does not use scale for equality. Here is a BigDecimal equals check for zero or not. import java.math.BigDecimal; public class BigDecimalTest { public static void main(String[] args) { BigDecimal bd = new BigDecimal(0); System...
In this article, we saw some algorithms to check whether a string is a rotation of another string. We saw how to search for common characters and assert equality using a doubled-origin string and thecontains()string method. Similarly, we can use algorithms to check whether the remaining part...
