Answer:
This article shows how to use regex to remove spaces in between a String.
A string with spaces in between.
String text = "Hello World Java.";
We want to remove the spaces and display it as below:
Hello World Java.
1. Java regex remove spaces
In Java, we can use regex \\s+ to match whitespace characters, and replaceAll("\\s+", " ") to replace them with a single space.
Regex explanation.
`\\s` # Matches whitespace characters.
+ # One or more
StringRemoveSpaces.java
package com.mkyong.regex.string;
public class StringRemoveSpaces {
public static void main(String[] args) {
String text = "Hello World Java.";
String result = text.replaceAll("\\s+", " ");
System.out.println(result);
}
}
Output
Terminal
Hello World Java.
Answer:
The following codes are:
int monthOfYear=11;
// integer type variable is initialized
long companyRevenue=5666777;
// long type variable is initialized
int firstClassTicketPrice=6000;
// integer type variable is initialized
long totalPopulation=1222333; //// long type variable is initialized
Explanation:
Here, we define integer type variable "monthOfYear" to 11.
Then, we define long type variable "companyRevenue" to 5666777.
Then, we define integer type variable "firstClassTicketPrice" to 6000.
Then, we define long type variable "totalPopulation" to 1222333.
Answer:
import java.util.Arrays;
import java.util.Scanner;
public class num4 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("How many numbers? ");
int n = in.nextInt();
int []intArray = new int[n];
//Entering the values
for(int i=0; i<intArray.length;i++){
System.out.println("Enter the numbers");
intArray[i]=in.nextInt();
}
System.out.println(Arrays.toString(intArray));
int min =intArray[0];
for(int i =0; i<intArray.length; i++){
if(min>intArray[i]){
min = intArray[i];
}
}
System.out.println("The Minimum of the numbers is "+min);
}
}
Explanation:
- Using Java programming language
- Prompt the user for the number of values
- Using Scanner class receive and store in a variable
- Create an array of size n
- Using an for loop continuously ask the user to enter the integers
- Print the array of integers
- Using another for loop with an if statement, find the smallest element in the array of numbers
- Output the the smallest number
