Question: Lab1: Write a class, xxxx StringLab1 (where xxxx is your Kean id), with a main method. Include th……

But i have written the following program in Java with the use of String methods. Before that please find the below String methods in java which are used in the following program.

1. int length() – It returns count of total number of characters in the String.

2. String toLowerCase() – It returns the string in lowercase letter. In other words, it converts all characters of the string into lower case letter.

3. String toUpperCase() – It returns the string in uppercase letter. In other words, it converts all characters of the string into upper case letter.

4. String substring(0,6) – It returns the substring of the string starting index of 0 and ending index with 6. Note here it will not return you the character at 6th index. It will return string from 0 to 5th indices.

5. String  substring(6) – It will return substring of the string strting from index 6 until the end of the string.

6. 7. & 8. int indexOf(‘U’) – It will return the index of the letter ‘U’. Note here that this will return first occurance of the character in the string.

It is case sensitive(treats ‘U’ and ‘u’ as different). If it not finds any occurance of the character then it reurns -1.

9. String replace(“University”,”U”) – It will return the new string which is replaced “Uniuversity” with letter “U”.

Program – class name is xxxx_StringLab1

public class xxxx_StringLab1 {

public static void main(String[] args) {

// Below will initalize the string variable str to Kean University

String str = “Kean University”;

//used length() to get the number of characters in the string

System.out.println(“The number of character is ” + str.length());

//used toLowerCase() to covert all the characters in the string to lower case

System.out.println(“The String in lower case is ” + str.toLowerCase());

//used toUpperCase() to covert all the characters in the string to upper case

System.out.println(“The String in upper case is ” + str.toUpperCase());

//used substring(0,6) to get first six characters of the string

System.out.println(“The first six characters of the string is “+str.substring(0, 6));

//used substring(0,6) to get remaining characters of the string

System.out.println(“The rest of the characters in the string are “+str.substring(6));

//used indexOf() to get the index of U

System.out.println(“The U in the string is at position “+str.indexOf(‘U’));

//used indexOf() to get the index of U

System.out.println(“The u in the string is at position “+str.indexOf(‘u’));

//used indexOf() to get the index of U

System.out.println(“The o in the string is at position “+str.indexOf(‘0’));

//used replace() to replace University with U

System.out.println(“The new String where University is replaced with U “+str.replace(“University”, “U”));

//Original String

System.out.println(“The Original String has not changed “+str);
