Call method(s) within the same class

Call method(s) within the same class

I am new to programming and Java. I am trying to make 3 methods. One gets the largest number, one gets the middle, and the last gets the smallest. I do not think I created them correctly. I am getting a compiler error in Jgrasp saying illegal start to expression for
each method. Then how do I call them? Here is my code:

Code :

import java.util.*;
 
public class Ch4_PrExercise2
{
	public static void main(String [] args)
	{
		Scanner console = new Scanner(System.in);
 
		int num1, num2, num3;
 
		System.out.println("Please input 3 numbers separated by spaces: ");
		System.out.println();
 
		num1 = console.nextInt();
		num2 = console.nextInt();
		num3 = console.nextInt();
 
 
 
			public int largest()
			{
				if(num1 > num2 && num1 > num3)			
					return num1;			
				else if(num2 > num1 && num2 > num3)			
					return num2;				
				else if(num3 > num1 && num3 > num2)
					return num3;
			}						
 
 
 
			public int smallest()
			{
				if(num1 < num2 && num1 < num3)
					return num1;
				else if(num2 < num1 && num2 < num3)
					return num2;
				else if(num3 < num1 && num3 < num2)
					return num3;
		   }
 
			 public int middle()
			 {
 
				if((num1 < num2 && num1 >num3) || (num1 > num2 && num1 < num3))
					return num1;
				else if((num2 > num1 && num2 < num3) || (num2 < num1 && num2 >num3))
					return num2;
				else if((num3 > num2 && num3 < num1) || (num3 < num2 && num3 > num1))
					return num3;
			 }
 
 
		System.out.println("Your numbers in nondescending order are: " + " " + smallest() + " " + middle() + " " largest());		
 
 
	}
}

thanks in advance

Re: Call method(s) within the same class

try this:

Code Java:

import java.util.*;
 
	public class TestIf
	{
		public static void main(String [] args)
		{
			Scanner console = new Scanner(System.in);
 
			int num1, num2, num3, smallest, largest, middle;
 
			System.out.println("Please input 3 numbers separated by spaces: ");
			System.out.println();
 
			num1 = console.nextInt();
			num2 = console.nextInt();
			num3 = console.nextInt();
 
			smallest= smallest(num1, num2, num3);
			largest= largest(num1, num2, num3);
			middle= middle(num1, num2, num3);
 
 
			System.out.println("Your numbers in nondescending order are: " + " " + smallest + " " + middle + " " + largest);		
 
 
		}
 
 
 
				public static int largest(int num1, int num2, int num3)
				{
					if(num1 > num2 && num1 > num3)			
						return  num1;			
					else if(num2 > num1 && num2 > num3)			
						return num2;				
					else if(num3 > num1 && num3 > num2)
						return num3;
					return 0;
				}						
 
 
 
				public static int smallest(int num1, int num2, int num3)
				{
					if(num1 < num2 && num1 < num3)
						return num1;
					else if(num2 < num1 && num2 < num3)
						return num2;
					else if(num3 < num1 && num3 < num2)
						return num3;
					return 0;
			   }
 
				 public static int middle(int num1, int num2, int num3)
				 {
 
					if((num1 < num2 && num1 >num3) || (num1 > num2 && num1 < num3))
						return num1;
					else if((num2 > num1 && num2 < num3) || (num2 < num1 && num2 >num3))
						return num2;
					else if((num3 > num2 && num3 < num1) || (num3 < num2 && num3 > num1))
						return num3;
					return 0;
				 }
 
 
 
	}

Re: Call method(s) within the same class

Did you make sure to change the class name back? I changed it so it would work in my project

Bertorox, it's good that you helped him, but next time better not feed spoon. You must stick with the forum rules.
Thanks
