How do you find the max of 3 elements in Java?

First, the three numbers are defined. If num1 is greater than num2 and num3, then it is the maximum number. If num2 is greater than num1 and num3, it is the maximum number. Otherwise, num3 is the maximum number.

### How do you do an addition program in Java?

1. int a = 12;
2. int b = 17;
3. int c = 342;
4. int d = a + b + c;
5. System. out. println(“Addition result = ” + d);

How do you find the minimum of 3 numbers in Java?

Algorithm

1. Start.
2. Take three numbers in a, b, c.
3. Check if a is less than b and a is less than c.
4. If above condition is true, a is smallest and go to step 7, else go to step 5.
5. Check if b is less than c.
6. If above condition is true, b is the smallest, else c is the smallest.
7. Stop.

#### How do you find the sum in Java?

Finding the sum of two numbers means the simple addition of both the numbers.

1. Create a separate variable to store the value of the sum. This can be of the type int.
2. The formula to find the sum is: Sum = First Number + Second Number.
3. To get these parameters (inputs) from the user, try using the Scanner function in Java.

How do you find the 3 maximum number of an array?

Solution Approach if (arr[i] > max) -> max3 = max2, max2 = max , max = arr[i]. else if (arr[i] > max2) -> max3 = max2, max2 = arr[i]. else if (arr[i] > max3) -> max3 = arr[i]. At the end of the loop, we will print all three values.

## How do you find the largest number with 3 numbers?

C Program to Find the Largest Number Among Three Numbers

1. Take the three numbers as input.
2. Check the first number if it is greater than other two.
3. Repeat the step 2 for other two numbers.
4. Print the number which is greater among all and exit.

How do you add numbers to a String in Java?

Algorithm:

1. Take a String.
2. Convert it into array of characters.
3. Apply for loop till length of char array.
4. Using isDigit() method we can check the digits in string.
5. If isDigit() will return true then print that index value.
6. That digit is in char form.
7. Using sum variable, we will sum it.

### How do you find the minimum value of 3 numbers?

We shall follow these steps to find the smallest number of three.

1. Read first number to a.
2. Read second number to b.
3. Read third number to c.
4. If a is less than b and a is less than c, then a is the smallest of the three numbers.
5. If b is less than a and b is less than c, then b is the smallest of the three numbers.

What is ternary operator in Java with example?

Java ternary operator is the only conditional operator that takes three operands. It’s a one-liner replacement for the if-then-else statement and is used a lot in Java programming. We can use the ternary operator in place of if-else conditions or even switch conditions using nested ternary operators.

#### How do you add numbers in a range in Java?

1. you could do sum += i instead of sum = sum + i.
2. your assignments of the lower and upper parameter values to the class fields with this.
3. you should move your println statement to print the sum after it is incremented.
4. you should consider returning sum as the method’s output:

How do you find the largest number in an array in Java?

Find Largest Number in Array using Collections

1. import java.util.*;
2. public class LargestInArrayExample2{
3. public static int getLargest(Integer[] a, int total){
4. List list=Arrays.asList(a);
5. Collections.sort(list);
6. int element=list.get(total-1);
7. return element;
8. }

## How do you find the first second and third largest number in an array?

First, iterate through the array and find maximum. Store this as first maximum along with its index. Now traverse the whole array finding the second max, excluding the maximum element. Finally traverse the array the third time and find the third largest element i.e., excluding the maximum and second maximum.

How do you find the second largest number in three numbers in Java?

Find 2nd Largest Number in Array using Arrays

1. import java.util.Arrays;
2. public class SecondLargestInArrayExample1{

5. return a[total-2];
6. }
7. public static void main(String args[]){
8. int a[]={1,2,5,6,3,2};

### How do you find the largest and smallest number in Java?

How To Find the Largest and Smallest Value in Java
