Hoping you can help me. So I have to read in a .txt file (which contains 100 names), and store them as arrays. I made a new String array and reserved 100 memory spots. Would I have to declare each element of the array one by one? Meaning that I have to list every single name inside my program?

How to compare 2 string arrays? For example:

String a[] = {“animal”, “food”, “place”};
String b[] = {“dog”, “cake”, ”japan”};

If (a[0].equals(b[0])){
//print Animal }

I know that .equals() won’t work for String arrays. I hope you help me with this!! Thank you for this video by the way 😊

public static void main(String[] args) {
String daysOfWeek [] = {"Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"};
for (int i = 0; i < daysOfWeek.length; i++);{
System.out.println( daysOfWeek[i] );
//I am using this code to print string array and getting error
"Exception in thread "main" java.lang.Error: Unresolved compilation problem:
i cannot be resolved to a variable"
please help to fix it.

How do you convert an array of multiple strings into one big string?

Can you please show the same input from console?? I mean taking input strings from console as a sentence and making them an array of words??

Do you have a video where you fill the array with user input? Great stuff thanks!

Thanks. How would I select an array at random, then display it? eg

var array = "array2" // pretend this was randomly chosen
String array1 = stuff, stuff2
String array2 = more, more2
String array3 = again, again2
System.out.println($array.2)
// I want to print out "more2"

public static void main (String [] args){
int things = 0;
boolean loop1 = true ;
char coba;
String i[] = new String[3];

Scanner sc = new Scanner(System.in) ;

do {
i[things] = sc.nextLine() ;
things++ ;

System.out.println("again?? (y/n)");
coba = sc.next().charAt(0);
if(coba == 'n' || coba == 'N') {
loop1 = false ;

}
}while(loop1);
}

so, i was trying to make user may input at least 1, and max 3 times name.
but it ended like this...
