In this Java Program, we have to find the largest number of three given numbers.
For Example :Input : 5 3 9
Output : 9
Java Program to find maximum of three numbers using if else statement
Let A, B and C be three given numbers
- First compare A and B.
- If A > B, then print the maximum of A and C.
- Else If A < B, then print the maximum of B and C.
package com.tcc.java.programs;
import java.util.Scanner;
public class MaximumThreeNumbers {
public static void main(String[] args) {
int a, b, c, max;
Scanner scanner;
// Take three integer from user
scanner = new Scanner(System.in);
System.out.println("Enter Three Integer");
a = scanner.nextInt();
b = scanner.nextInt();
c = scanner.nextInt();
// Using if-else statement compare a, b and c
if (a > b) {
// compare a and c
if (a > c)
max = a;
else
max = c;
} else {
// compare b and c
if (b > c)
max = b;
else
max = c;
}
System.out.println("Largest Number : " + max);
}
}
Output
Enter Three Integer 8 3 9 Largest Number : 9
Enter Three Integer -2 0 2 Largest Number : 2
Java Program to find maximum of three numbers using method
Let A, B and C be three given numbers and "getMax" be a function which takes two numbers as arguments and returns the maximum one.
- Find the maximum of A and B by calling getMax function. Let the maximum of A and B be X. (X = getMax(A, B));
- Now, compare X and C by calling getMax function and print the maximum of the two on screen.
- In this algorithm, we will call getMax function twice.
package com.tcc.java.programs;
import java.util.Scanner;
public class MaximumThreeNumbersFunction {
public static void main(String[] args) {
int a, b, c, max;
Scanner scanner;
// Take three integer from user
scanner = new Scanner(System.in);
System.out.println("Enter Three Integer");
a = scanner.nextInt();
b = scanner.nextInt();
c = scanner.nextInt();
max = getMax(getMax(a, b), c);
System.out.println("Largest Number : " + max);
}
public static int getMax(int num1, int num2) {
if (num1 > num2) {
return num1;
} else {
return num2;
}
}
}
Output
Enter Three Integer 6 1 0 Largest Number : 6
Enter Three Integer 3 -8 2 Largest Number : 3
