Java basic exercise - three numbers to compare the size

if else statement judgment

public static int maxIfElse(int num1, int num2, int num3){  
      
    if(num1>num2 && num1>num3){  
        return num1;  
    }else if(num2>num3){  
        return num2;  
    }else{  
        return num3;  
    }  
}  

Miki operator judgment:

public static void printMax(int a,int b,int c){  
    int max=(a>b?a:b)>c?(a>b?a:b):c;  
    System.out.println("The maximum number is: "+max);   
}  

variable parameter:

public static void printMax(int ... a){  
    int max = a[0];  
    for(int i =1;i<a.length;i++){  
        if(a[i]>max){  
            max = a[i];  
        }  
    }  
    System.out.println("The maximum number is: "+max);   
      
}
