Java Program to Calculate Simple Interest

Leave a Comment / Basic / By Neeraj Mishra

Here you will get java program to calculate simple interest. We can calculate simple interest in java by using following formula. Simple Interest = (Principle x Rate x Time) / 100 Also Read: Java Program to Calculate Compound Interest

import java.util.Scanner;

public class JavaSimpleInterest {
	public static void main(String args[]){
		float p, r, t, si;
		Scanner sc = new Scanner(System.in);
		
		System.out.print("Enter principle: ");
		p = sc.nextFloat();
		
		System.out.print("Enter rate: ");
		r = sc.nextFloat();
		
		System.out.print("Enter time: ");
		t = sc.nextFloat();
		
		si = (p * r * t) / 100;
		
		System.out.print("\nSimple Interest = " + si);

	}
}

import java.util.Scanner;

public class JavaSimpleInterest {

public static void main(String args[]){

float p, r, t, si;

Scanner sc = new Scanner(System.in);

System.out.print("Enter principle: ");

p = sc.nextFloat();

System.out.print("Enter rate: ");

r = sc.nextFloat();

System.out.print("Enter time: ");

t = sc.nextFloat();

si = (p * r * t) / 100;

System.out.print("\nSimple Interest = " + si);

}

Output Enter principle: 1000 Enter rate: 3 Enter time: 2 Simple Interest = 60.0

How to Split String in Java with Example

Leave a Comment / String / By Neeraj Mishra

Here you will learn how to split string in java. We can split string in Java using split() method of java.lang.String class. It takes a regular expression as an argument and returns an array of strings. Syntax:

public String[] split(String regex)

1	public String[] split(String regex)

Split String in Java Example Below program will split the string by space.

public class SplitStringJava {
	public static void main(String...s){
		String str = "I Love Java Programming";
		String strArray[] = str.split("\\s");  //split by space
		
		for(int i=0;i<strArray.length;++i){
			System.out.println(strArray[i]);
		}
	}
}

public class SplitStringJava {

public static void main(String...s){

String str = "I Love Java Programming";

String strArray[] = str.split("\\s"); //split by space

for(int i=0;i<strArray.length;++i){

System.out.println(strArray[i]);

}

Output …
