how to calculate the length of a string without spaces in java
提问by Big Moe Pasha
this calculate the whole length of the string eg i am a man= 7 letter and 9 characters i just want the amount of the total letters
这计算了字符串的整个长度，例如我是一个人 = 7 个字母和 9 个字符我只想要总字母的数量
import java.util.Scanner;
public class AssignmentProgramming {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner sc = new Scanner(System.in);
System.out.println("Please enter a string");
String input = sc.nextLine();
System.out.println(input);
String str = input;
String[] myString = str.split(" ");
int length = str.length();
System.out.println(length);
}
}

You could try replacing all empty spaces by zero char:
您可以尝试用零字符替换所有空格：
String test = "Hello world 1 2 3 4 5";
System.out.println(test.replace(" ", "").length());

int characters = 0;
for (int i = 0, length = string.length(); i < length; i++) {
if (str.charAt(i) != ' ') {
characters++;
}
}

import java.util.*;
class cont
{
public static void main(String arg[]){
int sum=0;
Scanner s=new Scanner(System.in);
System.out.println("please enter string");
String val=s.nextLine();
int len=val.length();
for(int i=0;i<len;i++){
if(val.charAt(i)==' ')
{
continue;
}
sum++;
}
System.out.println(sum);
}
}

Let me know if this helps you out !!
如果这对您有帮助，请告诉我！！
import java.util.*;
public class CountCharacters
{
public static void main(String[] args)
{
System.out.println("Entered a string ");
Scanner sc= new Scanner(System.in);
String originalString=sc.nextLine();
System.out.println("Entered string is "+originalString);
String newString=originalString.replaceAll(" ", "");
System.out.println("New string after removing spaces is "+newString);
System.out.println("Number of characters in string are "+newString.length());
}
}
