Q.1 Write a Java method to find the smallest number among three numbers.

Solution  :- 

import java.util.*;

class findsmall

{

public static double smallest(double x , double y , double z)

{

return Math.min(Math.min(x,y),z);

}

}

class Main1

{

public static void main(String args[])

{

Scanner in = new Scanner(System.in);

int x,y,z;

System.out.println(“Enter the First number :- “);

x = in.nextInt();

System.out.println(“Enter the Second number :- “);

y = in.nextInt();

System.out.println(“Enter the Third number :- “);

z = in.nextInt();

findsmall s1 = new findsmall();

double m1 = s1.smallest(x,y,z);

System.out.println(“The Smallest number is :-  “+m1);

}

}
