Question

Write a Java Program

Math.sqrt(). Calculate the square roots of 1, 2, 3, 4 to three decimal places. Print a column header " n sqrt(n)" and use the printf() method.

Answer 1

public class Main {

        public static void main(String[] args) {

                System.out.printf("%-10s%-10s\n", "N", "SQRT(N)");
                
                for(int i=1; i<=4; i++) {

                        System.out.printf("%-10d%-10.2f\n", i, Math.sqrt(i));
                        
                }
                
        }

}

public class SquareRootCalculator {
    public static void main(String[] args) {
        // Print column headers
        System.out.printf("%-5s %-8s%n", "n", "sqrt(n)");
        System.out.println("-----------");
        
        // Calculate and print square roots for numbers 1 through 4
        for (int n = 1; n <= 4; n++) {
            double sqrt = Math.sqrt(n);
            System.out.printf("%-5d %-8.3f%n", n, sqrt);
        }
    }
}
