# Java Program to Find the Largest Among Three Numbers ## What is Number ?

An item in mathematics used for measurement, counting, and labelling is a number. Many categories can be used to categorise numbers, including natural, whole, integer, rational, irrational, real, and complex numbers. They carry out computations and offer solutions in a number of mathematical operations, including addition, subtraction, multiplication, and division.

## Steps to Find the Largest Among Three Numbers :

1. Put the three numbers in variables after taking them as input.
2. In a new variable, let’s call it “temp,” compare the first and second numbers and store the greater one there.
3. If the third number is greater than the “temp” variable, compare the two numbers and put the higher value in the “temp” variable.
4. The “temp” variable now has the biggest number of the three. As output, print the value of the variable “temp.”

### Pseudo Code for the above algorithm :

```Input: three numbers a, b, c

temp = a
if b > temp:
temp = b
if c > temp:
temp = c

Output: temp
```

### Example 1 :

Run
```import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int a, b, c, largest;

System.out.print("Enter the first number: ");
a = input.nextInt();

System.out.print("Enter the second number: ");
b = input.nextInt();

System.out.print("Enter the third number: ");
c = input.nextInt();

largest = a;
if (b > largest) {
largest = b;
}
if (c > largest) {
largest = c;
}

System.out.println("The largest number is " + largest);
}
}
```

### Output :

```Enter the first number: 12
Enter the second number: 17
Enter the third number: 5
The largest number is 17
```

### Example 2 :

Run
```public class Main {
public static void main(String[] args) {
int a = 10, b = 20, c = 30, largest;

if (a > b) {
if (a > c) {
largest = a;
} else {
largest = c;
}
} else {
if (b > c) {
largest = b;
} else {
largest = c;
}
}

System.out.println("The largest number is " + largest);
}
}

```

### Output :

```The largest number is 30
```
