Example 2: Program to find largest number among three numbers using nested if
public class JavaExample{
public static void main(String[] args) {
int num1 = 10, num2 = 20, num3 = 7;
if(num1 >= num2) {
if(num1 >= num3)
/* This will only execute if conditions given in both
* the if blocks are true, which means num1 is greater
* than num2 and num3
*/
System.out.println(num1+" is the largest Number");
else
/* This will only execute if the condition in outer if
* is true and condition in inner if is false. which
* means num1 is grater than num2 but less than num3.
* which means num3 is the largest
*/
System.out.println(num3+" is the largest Number");
}
else {
if(num2 >= num3)
/* This will execute if the condition in outer if is false
* and inner if is true which means num3 is greater than num1
* but num2 is greater than num3. That means num2 is largest
*/
System.out.println(num2+" is the largest Number");
else
/* This will execute if the condition in outer if is false
* and inner if is false which means num3 is greater than num1
* and num2. That means num3 is largest
*/
System.out.println(num3+" is the largest Number");
}
}
}
Output:
20 is the largest Number
Explanation:
Example 1: Finding largest of three numbers using if-else..if
public class JavaExample{
public static void main(String[] args) {
int num1 = 10, num2 = 20, num3 = 7;
if( num1 >= num2 && num1 >= num3)
System.out.println(num1+" is the largest Number");
else if (num2 >= num1 && num2 >= num3)
System.out.println(num2+" is the largest Number");
else
System.out.println(num3+" is the largest Number");
}
}
Output:
20 is the largest Number
