Learn Java - Exercise 01x - Methods in Java

Learn how to program in java with our online tutorial. We will cover variables, loops, if else branching, arrays, strings, objects, classes, object oriented programming, conditional statements, and more.

Here we get practice writing code that involve the use of methods in java.

I don't have any kind of method to return my "Gratitude" into your method.. It's all void.



UR THE BEST

You can also switch case and call the methods from another class.

[myimmortal]

package Method;
import java.util.Scanner;
public class Methods {

public static void main(String[] args) {
int number =0;

System.out.println(" hi enter a number ");

Scanner input= new Scanner(System.in);

number= input.nextInt();

if (number==1) {
spring();}
else if ( number ==2 )
summer();
else if ( number ==3)
autum();
else if ( number == 4)
winter();
else System.out.println( " be sure the number from 1 to 4");

}


public static void spring() {
System.out.println( " it is spring");
}
public static void summer () {
System.out.println( " it is summer ");
}
public static void autum () {
System.out.println( " it is autum ");}
public static void winter ()
{
System.out.println( " it is winter ");}

}

you have made java interesting for me, just when i was almost giving up on it..can't seem to find anything on arrays. if you could please help with that as well... Bless up.

I am glad I tried the exercises first. I used method to write my code since we are learning about method. If anyone wants to see my code, I'll post it.

to every CS student checking the comments to see if this is worth watching









public static void printRecommendation(){

System.out.println("this is the best");


}

do {

switch(userInput) {
case 1: printSpring();
break;
case 2: printSummer();

case 3: printFall();
break;
case 4: printWinter();

break;
}
}while((userInput < 1) || (userInput > 4));
}

public static void printSpring() {
System.out.println("The season is Spring, and the flowers are blooming!");
}

public static void printSummer() {
System.out.println("The season is Summer, and it is getting hot!");
}

public static void printFall() {
System.out.println("The season is Fall, and leaves are falling!");
}

public static void printWinter() {
System.out.println("The season is Winter, and it is snowing!");
}

}

What is wrong here because does not work
