Finding Maximum of Three Integers in Java

Finding maximum of three integers problem helps to understand if-else branching and conditionals topic in a better way.

Following is the implementation of the find maximum of three integers in Java.

package basics;

public class ThreeComparator {

 public static int max3( int a, int b, int c )
 {
  if( a>b )
  {
   if( a > c )
       return a;
   else
       return c;
  }
  else if( b>c )
  {
                 return b;
  }
  else
  {
   return c;
  }
  
 }
 
 public static void main(String[] args) {
  
  int a = 4;
  int b = 3;
  int c = 5;
  
  System.out.println("Maximum of "+a+" , "+b+" and "+c+" is = "+max3( a,b,c ));
  System.out.println("Maximum of "+a+" , "+c+" and "+b+" is = "+max3( a,c,b ));
  System.out.println("Maximum of "+b+" , "+a+" and "+c+" is = "+max3( b,a,c ));
  System.out.println("Maximum of "+b+" , "+c+" and "+a+" is = "+max3( b,c,a ));
  System.out.println("Maximum of "+c+" , "+a+" and "+b+" is = "+max3( c,a,b ));
  System.out.println("Maximum of "+c+" , "+b+" and "+a+" is = "+max3( c,b,a ));
  
  System.out.println("Maximum of 4 , 5 and 4 is = "+max3( 4,5,4 ));
  System.out.println("Maximum of 41 , 41 and 41 is = "+max3( 41,41,41 ));
  System.out.println("Maximum of 11 , 21 and 31 is = "+max3( 11,21,31 ));  
 }
}

Create a ThreeComparator.java file in your workspace.

When the main method inside the ThreeComparator class executed it is going to print :

Maximum of 4 , 3 and 5 is = 5
Maximum of 4 , 5 and 3 is = 5
Maximum of 3 , 4 and 5 is = 5
Maximum of 3 , 5 and 4 is = 5
Maximum of 5 , 4 and 3 is = 5
Maximum of 5 , 3 and 4 is = 5
Maximum of 4 , 5 and 4 is = 5
Maximum of 41 , 41 and 41 is = 41
Maximum of 11 , 21 and 31 is = 31
