Find upper and lower case from string.
As a Systems Engineer at Tata Consultancy Services, I deliver exceptional software products for mobile and web platforms, using agile methodologies and robust quality maintenance. I am experienced in performance testing, automation testing, API testing, and manual testing, with various tools and technologies such as Jmeter, Azure LoadTest, Selenium, Java, OOPS, Maven, TestNG, and Postman.
I have successfully developed and executed detailed test plans, test cases, and scripts for Android and web applications, ensuring high-quality standards and user satisfaction. I have also demonstrated my proficiency in manual REST API testing with Postman, as well as in end-to-end performance and automation testing using Jmeter and selenium with Java, TestNG and Maven. Additionally, I have utilized Azure DevOps for bug tracking and issue management.
Write a Java program to find the upper and lower case from string and print count.
import java.util.*;
import static java.lang.System.in;
public class demo {
public static void main(String[] args) {
String str = "Gulshan Kumar";
int len = str.length();
String capsString = "";
String smallString = "";
int small = 0;
int caps = 0;
for (int i=0; i<len; i++){
// The range A-Z is mapped to [65-90]
// nd [a-z] is mapped to [97-122]
if (str.codePointAt(i)>64 && str.codePointAt(i)<91){
capsString += str.charAt(i)+" ";
caps++;
} else if (str.codePointAt(i)>96 && str.codePointAt(i)<123) {
smallString += str.charAt(i)+" ";
small++;
}
}
System.out.println("Small letters in String are : "+smallString +
"\nand count of the letters is : "+ small);
System.out.println("***********************************");
System.out.println("Capital letters in String are : "+capsString +
"\nand count of the letters is : "+ caps);
}
} // main block
/*
output
Small letters in String are : u l s h a n u m a r
and count of the letters is : 10
***********************************
Capital letters in String are : G K
and count of the letters is : 2
