Java Program - Find Smallest Number among three Numbers
Three numbers x, y and z are given and the smallest number among these three numbers can be found out using below methods.
Example: Using If statement
In the below example, only if conditional statements are used.
public class MyClass {
static void smallest(int x, int y, int z) {
int min = x;
if (x <= y && x <= z)
{min = x;}
if (y <= x && y <= z)
{min = y;}
if (z <= x && z <= y)
{min = z;}
System.out.println("Smallest number among " + x + ", " + y + " and " + z + " is: " + min);
}
public static void main(String[] args) {
smallest(100, 50, 25);
smallest(50, 50, 25);
}
}
The above code will give the following output:
Smallest number among 100 , 50 and 25 is: 25 Smallest number among 50 , 50 and 25 is: 25
Example: Using If-else statement
It can also be solved using If-else conditional statements.
public class MyClass {
static void smallest(int x, int y, int z) {
int min = x;
if (x <= y && x <= z)
{min = x;}
else if (y <= x && y <= z)
{min = y;}
else
{min = z;}
System.out.println("Smallest number among " + x + ", " + y + " and " + z + " is: " + min);
}
public static void main(String[] args) {
smallest(100, 50, 25);
smallest(50, 50, 25);
}
}
The above code will give the following output:
Smallest number among 100 , 50 and 25 is: 25 Smallest number among 50 , 50 and 25 is: 25
Example: Using Nested If-else statement
The above problem can also be solved using nested if-else conditional statements.
public class MyClass {
static void smallest(int x, int y, int z) {
int min = x;
if (x <= y)
{
if(x <= z)
{min = x;}
else
{min = z;}
}
else
{
if(y <= z)
{min = y;}
else
{min = z;}
}
System.out.println("Smallest number among " + x + ", " + y + " and " + z + " is: " + min);
}
public static void main(String[] args) {
smallest(100, 50, 25);
smallest(50, 50, 25);
}
}
The above code will give the following output:
Smallest number among 100 , 50 and 25 is: 25 Smallest number among 50 , 50 and 25 is: 25
Example: Using ternary operator
The ternary operator can also be used here.
public class MyClass {
static void smallest(int x, int y, int z) {
int min = x;
min = (x < y)? ((x < z)? x : z) : ((y < z)? y : z);
System.out.println("Smallest number among " + x + ", " + y + " and " + z + " is: " + min);
}
public static void main(String[] args) {
smallest(100, 50, 25);
smallest(50, 50, 25);
}
}
The above code will give the following output:
Smallest number among 100 , 50 and 25 is: 25 Smallest number among 50 , 50 and 25 is: 25
