}
}

Answer 1

Hi, sorry for the delay, I was knocked out for hours, well, I have re-test the code, I am guessing you might have invalid character copied along with the code probably, that might be the cause for compilation error. Can you run this again just to check:

public class Program
{
public static void main(String[] args) {
int[] a=new int[5];

for(int i=0; i<a.length;i++){
a[i]=i+1;
System.out.println("a[" + i + "]=" + a[i]);
}
}
}

You can find me in SoloLearn Discord server, there are more Java knowledgeable people there too, see this thread for more info about Discord:

Answer 2

You forgot to add curly braces to wrap the for loop body, remember when there are more than one instructions line in a block you need to wrap them in curly braces : )

public class Java{
public static void main(String[] args) {
int[] a=new int[5];

for(int i=0; i<a.length;i++){
a[i]=i+1;
System.out.println("a[" +i+"]" + "="+a[i]);
}
}
}

Hth, cmiiw

Oh, sorry about that Hunt , can you tell me if you get any error message running the code? I tried to run that code in Code Playground and got result as follows:

a[0]=1
a[1]=2
a[2]=3
a[3]=4
a[4]=5

Maybe we'll work something out, come and talk to me : )

Answer 5

Yeah i follow your way to do it,but the output of my program always show "Compilation error". This is my program👇👇👇👇

public class Program
{
public static void main(String[] args)  {

     int[] a=new int[5];

     for(int i=0; i<a.length;i++){
     a[i]=i+1;
     System.out.println("a[" +i+"]" + "="+a[i]);
     }
}
}

By the way,how can i talk to you personnally😂
