im sure this advise has been given to you now multiple times in a few different threads so hopefully this will wrap it up for you
public static void main(String[] args){
while(true){
            System.out.println("What do you want to perform choose :\n 1. Searching\n 2. Sorting\n 3. Exit\n ");
            Scanner input = new Scanner(System.in);
                    switch(input.nextInt()){
                        case 1 :
                                              linearsearch();         //calls your linearsearch method
                                             continue;                 //starts the loop again
                        case 2 :
                                            sorting();                    /calls your sortingmethod
                                             continue;                   //starts the loop again
                        case 3 :
                                             break;                                //exists the loop
                        default:           System.out.println(input.nextInt()+ "is not a valid charachter , please try again");
}//end of while loop
         }
