Maprogrammer nawezaje kutumia printf kwenye java mana kwenye vitabu wanaitumia sana ila kila nikijaribu inaniletea error,kuna nini kinachoweza kuleta error wakati code ipo vyema kwa kila kitu

 

[salito]

hebu iweke hiyo line ya code inayoleta error

 

[Abdulhalim]

tuwekee hiyo code tuione basi

 

[The hammer]

mfano
System.out.printf("Welcome to java progrmming language\n%s!\n"getCourseName);
Hapo error inakuwa kwenye f.
NOTE:

Then hata nikitumia statement ifuatayo inasumbua:

final int ARRAY_LENGTH=10;
int counter;
int array[]=new int[ARRAY_LENGTH];
for(counter=0; counter<array.length; counter++);
array[counter]=2+2*counter;
System.out.println("Index\tValue");
for(counter=0; counter<array.length; counter++);
System.out.println(counter);
Tatizo linakuwa kwny array.length...............WHY

public class Sample
{
public Sample(){}


public static void main(String []args)
{
final int ARRAY_LENGTH=10;
int counter;
int array[]=new int[ARRAY_LENGTH];
for(counter=0; counter<array.length; counter++)
array[counter]=2+2*counter;
System.out.println("Index\t Value");
for(counter=0; counter<array.length; counter++)
System.out.println(counter +"\t"+array[counter]);
}
}

Output
Index Value
0 2
1 4
2 6
3 8
4 10
5 12
6 14
7 16
8 18
9 20

ondoa semicolons kwenye for loops

Hiyo nimeiweka kimakosa tu,ila niliyoi-type kwenye comodo ipo sahihi,then iliyoirekebisha error inatokea kwenye

array.length............au jdk ninayotumia siyo

kwnn nikitumia hiyo printf na array.length inanikatalia...ni tatizo nimehangaika nalo mwezi sasa

 

[babuwaloliondo]

for(counter=0; counter<array.length; counter++);// presence of semicolon at the end of for loop: syntax error
array[counter]=2+2*counter;
System.out.println("Index\tVal ue");
for(counter=0; counter<array.length; counter++); // presence of semicolon at the end of for loop: syntax error
System.out.println(counter);//replace with this System.out.println(counter +"\t"+array[counter]);

Ndugu sidhani kama kuna tatizo kwenye array.length. Weka code au segment yenye printf() tuone cause ya tatizo.

System.out.printf("Welcome to java progrmming language\n%s!\n"getCourseName) ;

Weka comma before variable or method name unazo call kwenye printf() statement.

e.g: System.out.printf("Welcome to java progrmming language\n%s!\n" , getCourseName) ;


Pia hiyo getCourseName ni method au variable? kama ni method nadhani inapaswa iwe getCourseName().

array[counter]=2+2*counter;
System.out.println("Index\t Value");
for(counter=0; counter<array.length; counter++)
System.out.println(counter +"\t"+array[counter]);
}

Hii iko poa nimeijaribu inarun fresh, labda kama unatatizo jingine.

error gani?? Tupe habari kamili usaidiwe.

Nadhani hiyo method hauiiti sawa ni getName() sio getName kama ni method isiyo na parameters, pamoja na makosa waliyotaja wengine.

 

[Striker Searcher]

Nilikuwa najaribu kufuatilia syntax yako uliyotumia regarding to java recommended syntax. I've never ever come across pprintf() in java except in Cprogramming language. Ngoja nifuatilie then I'll back to you.

Duh! Bonge la giza, sijui nimepita huku kufanya nini.

 

[Mr.mzumbe]

wakuu kama kutakuwa na uwezekano ebu nitafutieni product ya even number kwenye code

 

[teac kapex]

Duh! Bonge la giza, sijui nimepita huku kufanya nini.

hata mimi sawa na kipofu sielewi hawa jamaa wanazungumzia nini

 

[Chimunguru]

DAh nilizipiga sana hizi code enzi zangu siku hizi nimekuwa mvivu sana

 

[BHULULU]

Duh! Bonge la giza, sijui nimepita huku kufanya nini.

Mkuu umenichekesha sana,mambo ya programming hayo!
