Explanation: In this blog post, we'll explore how to use Java 8's Stream API and Comparator to sort a list of Transaction objects first by their date attribute and then by their id attribute in case of a date tie Sample Code: java public class MultipleComparatorTest { private int id; private String txnType; private String date; public MultipleComparatorTest(int id, String txnType, String date) { this.id = id; this.txnType = txnType; this.date = date; } public int getId() { return id; } public String getDate() { return date; } @Override public String toString() { return "MultipleComparatorTest [id=" + id + ", txnType=" + txnType + ", date=" + date + "]"; } public static void main(String[] args) { List<MultipleComparatorTest> transactions = createTransactionList(); // Create your list of Transaction objects Comparat...
To find the second-highest salary from a list of employees using Java 8 streams, you can follow these steps: Create a list of employees with their salaries. Use Java 8 streams to sort the employees by salary in descending order. Skip the first element (which is the employee with the highest salary). Get the first element of the remaining stream (which is the employee with the second-highest salary). Example code: java import java.util.ArrayList; import java.util.List; class Employee { private String name; private double salary; public Employee (String name, double salary) { this .name = name; this .salary = salary; } public double getSalary () { return salary; } } public class SecondHighestSalary { public static void main (String[] args) { List<Employee> employees = new ArrayList <>(); employees.add( new Employee ( "John" , 60000.0 )); employees.add( new Employe...
