### Java assignment 5: Write the largest integer

Level: Normal

```import java.util.Scanner;

public class Math
{
void getLargest(int i, int i2, int i3)
{
// add the body of the method here!
}
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
System.out.print("Enter the first nr: ");
int i = input.nextInt();
System.out.print("Enter the second nr: ");
int i2 = input.nextInt();
System.out.print("Enter the third nr: ");
int i3 = input.nextInt();
Math math = new Math();
math.getLargest(i, i2, i3);
input.close();
}
}
/*
In the following example the user enters 34, 55 and 2
Enter the first nr: 34
Enter the second nr: 55

The body of the method is written in the following code.

This program asks the user to enter three numbers respectively and then the program calculates the largest number.

```import java.util.Scanner;

public class Math
{
void getLargest(int i, int i2, int i3)
{
if(i > i2 && i > i3)
System.out.println(i);
else if(i2 > i && i2 > i3)
System.out.println(i2);
else if(i3 > i && i3 > i2)
System.out.println(i3);
else System.out.println(""
+ "Enter unique numbers!");
}
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
System.out.print("Enter the first nr: ");
int i = input.nextInt();
System.out.print("Enter the second nr: ");
int i2 = input.nextInt();
System.out.print("Enter the third nr: ");
int i3 = input.nextInt();
Math math = new Math();
math.getLargest(i, i2, i3);
input.close();
}
}
