See my qes.

Question

class HelloWorld {
public static void main(String[] args) {
String s="abcdef";
char c[]=s.toCharArray();
for(int i=c.length-1;i==0;i--){
System.out.println(c[i]);}
}
}

class HelloWorld {
public static void main(String[] args) {
String s="abcdef";
char c[]=s.toCharArray();
for(int i=c.length-1;i==0;i--){
System.out.println(c[i]);}
}
}

Why "for(int i=c.length-1;i==0;i--)" for loop is not working here with i==0
And working with "for(int i=c.length-1;i>=0;i--)"
Why?

Answer 1

Knowing that
<i> is length of string - 1

Condition
<i> == 0 is not true. When condition evaluates to false even from the beginning, the loop doess not even get started.
