String is a sequence of character values. In Java, Strings are considered as objects. We have a String class provided by Java for creating and manipulating strings. We have to convert the first letter of the word to lowercase and last letter of the word to uppercase. In this article we will see how the first and last letter can be converted into lower and upper case respectively. Let’s explore. To Show You Some Instances Instance-1 Suppose the input string is “Hello” After converting the first letter to lower and last letter to capital, the new string will be “hellO” ... Read More
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find the sum of elements which is even and sum of elements which is odd in an array and compare their sum and check which one is smaller. A number is said to be even if it is divisible by 2 else it is called an odd number. Note − The array must be an integer array. Let’s explore the article to see how it can be done by using Java programming language. ... Read More
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find the sum of all even and odd numbers in a given array and compare them to see which one is greater. Note − The array must be an integer array. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose the original array is {14, 49, 55, 67, 72, 82} After finding average of sum of even and ... Read More
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to check and confirm the array is free from 0 and negative numbers. Let us say that an array contains 0 or a negative element then the result should pop up that "Array contains 0 or a negative number." Otherwise, the result should be "Array doesn’t contain 0 or a negative number." Note − The array must be an integer array. Let’s explore the article to see how it can be done by using ... Read More
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to arrange all elements of array such that negative elements are present before positive elements. If a number is greater than 0 then it is called as positive number, if less than 0 then it is called as negative number. Note − The array must be an integer array. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose the ... Read More

Introduction A blockchain is a disseminated information base or record that is divided between the hubs of a PC organization. As a data set, a blockchain stores data electronically in a computerized design. Blockchains are most popular for their pivotal job in digital money frameworks, like Bitcoin, for keeping a safe and decentralized record of exchanges. The development of a blockchain is that it ensures the devotion and security of a record of information and produces trust without the requirement for a confided-in outsider. One critical distinction between a normal information base and a blockchain is how the information is ... Read More
Blockchain is a perfect fit for the banking industry. Banks currently face several pain points: they rely on highly-specific banking experts and bankers, constantly battling cybersecurity risks and breaches, and their operations are overly complex. However, with blockchain, banks can operate more efficiently by connecting to smart contracts instead of relying on people. Blockchain also solves the issue of cybersecurity by making it impossible to hack. Finally, individual components can be isolated from one another so that if one fails, everything remains operational. Complexity is the enemy of efficiency, and complexity costs money. Although blockchain technology is complex, it removes ... Read More
