The problem we face in this post is to take a long string and split it in several lines of fixed length that will be displayed. str_size; i++) … For example: Given string: “Better to reduce time complexity” Given the value of N= 4; So, we have to divide this string into 4 equal parts. *; class Main { static void splitString(String str1, int n) { int str_size = str1.length(); int part_size; if (str_size % n != 0) { System.out.println("The size of the given string is not divisible by " + n); return; } else { System.out.println("The given string is: " + str1); System.out.println("The string divided into " + n + " parts and they are: "); part_size = str_size / n; for (int i = 0; i . If you omit the separator or the split() cannot find the separator in the string, the split() returns the entire string. The idea is to split the string using split() function and pass the resultant array into Arrays.asList() method which returns a fixed-size List backed by an array. You can use Java's substring function to divide them in halves: String s1a = s1.substring(0, (s1.length()/2)); String s1b = s1.substring((s1.length()/2); The split () method in Python returns a list of strings after breaking the given string by the specified separator. We can use LINQ’s Select method to split a string into substrings of equal size. In this post, we will see how to convert comma-separated String to List in Java. Solution. Advertisements.

Algorithm. dim length1 as string dim length2 as string dim lenght3 as string length1=Mid$(Text1.text, 1, 30) length2=Mid$(Text1.text, 30, 70) length3=Mid$(Text1.text, 70, 100) msgbox length1 msgbox lenght2 msgbox length3 msgbox 2 show me the length of 11,30.
