What is sub.string() ? In java

Answer 1

You are looking for something like this?

String str= new String("quick brown fox jumps over the lazy dog");

System.out.println("Substring starting from index 15:");
System.out.println(str.substring(15));

System.out.println("Substring starting from index 15 and ending at 20:");

System.out.println(str.substring(15, 20));

Answer 2

String a = "Learning java is fun";
System.out.println(a.substring(1,8));

From index 1 to index 8-1
So it will print "earning"

Edit: It will not print the character at the index 8.

Answer 3
