Java does "age" or "Age" matter when declaring an Int??
Hey this is my code, :newbie: stuff:
public class GMFnTFF {public static void main (String []args) {EasyReader r= new EasyReader (); int age; System.out.print ("Enter your name: "); String name= r.readLine (); System.out.print ("Enter your age: "); String LineAge= r.readLine (); int Age= Integer.parseInt (LineAge); ////here i tried doing age why ////doesnt that work? but Age does System.out.print ("Enter your weight: "); String weight1= r.readLine (); double weight= Double.parseDouble (weight1); System.out.print ("Greetings, "+name+". You are "+Age+" years old and you weight "+weight+" pounds."); } } int Age works int age doesnt why? what does age do in java? I am using j2sdk1.4.2 using the simple compiler bluejay and i am new if you cant tell so try to explain it easily. thx thanks in advance (ey, me crew do yourselves a fava and dont steal my program or else, ali g talk :D) also, i was updating this code for the last 1/2hr or so, and i found out that when i would type in String name= r.readLine (); it would automatically print the line to the output, does this always happen auto or is there a way to save a string and not print it immediatly? thanks again in advance (also the ali g talk meant dont steal my code, lol) |
Age and age are 2 different things because variables in java are case sensitive. age is just a variable and doesnt do anything in java.
String name= r.readLine (); it doesnt print to output, it reads a line and saves it under a string name. ..looks like u just got started with programming.. I think you should read a good book if u want to learn java. cool :) |
i try to make age a int, so your telling me all ints have to be lower case? i tried bge (lower case int) and that works, i guess i didn't understand, is age a reserved method(or something) like double?
also, String name= r.readLine (); saves a variable, but why does it print it to the output if i didn't ask it to. the output of this code is Enter your name: Laptop2250 Enter your age: 2250 Enter you weight: 225 Greetings, Laptop 2250. You are 2250 years old and you weight 225 pounds. the only thing i understand is that those strings/int/doubles should only appear in the last line (greetings) because i told the program to. why do the ints/strings/doubles appear other places? thanks again |
Here's my code that works (I changed the EasyReader class because I have an older JVM)
I think the problem is areound the line that I've flagged with /* >>> */ I think, judging from your code, you had declared age as an int at line /* LINE REF A */ and then re-declared it as an int on line /* >>> */ which is a nono... PS: I also used System.out.println because it will cause the output stream buffer to flush() automatically. plus it adds a newline character. Code:
