Question

我想将特定值分配给字母（下面的代码中），然后计算它由输入字符串提供的总增加输出，我没有得到。例如。 Kamran = 2 + 1 + 4 + 2 + 1 + 5 = 15或abc = 1 + 2 + 3 = 6。通过这段代码，我只得到最后一位数的输出。提前致谢！问候！！！

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;


public class p1 {

    static int addition;
    static char Kamran;
    static int string1;
    static int total;
    final static int a=1,b=2,c=3,d=4,e=5,f=8,g=3,h=5,i=1,j=1,k=2,l=3,m=4,n=5,o=7,p=8,q=1,r=2,s=3,t=4,u=6,v=6,w=6,x=5,y=1,z=7;

    public static void main(String[] args) throws IOException {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        String userInput = in.readLine();
        for(int ai=0;ai<userInput.length();ai++){
            string1 = (int)userInput.charAt(ai);
        }
        int adder=0;

        if(string1=='k')
            {adder = 2 + adder ; }
        if(string1=='a')
            {adder = 1 + adder ; }
        if(string1=='m')
            {adder = 4 + adder ; }
        if(string1=='r')
            {adder = 2 + adder ; }
        if(string1=='b')
            {adder = 2 + adder ; }
        if(string1=='n')
            {adder = 5 + adder ; }

        total=adder;
        System.out.println(total);
    }
}

Answer 1

尝试：

    public int desiredMethod(String input, Function<Character, Integer> conversion){
        String inputRevised = input.toLowerCase();
        int output = 0;
        for(int i=0 ; i<inputRevised.length() ; i++)
            output = output + conversion.apply(inputRevised.charAt(i));
        return output;
    }

这样，相同的方法可以使用多个地图字符»整数。

Answer 2

   int adder=0;
   for(int ai=0;ai<userInput.length();ai++){
        string1 = (int)userInput.charAt(ai);
    if(string1=='k')
        {adder = 2 + adder ; }
    if(string1=='a')
        {adder = 1 + adder ; }
    if(string1=='m')
        {adder = 4 + adder ; }
    if(string1=='r')
        {adder = 2 + adder ; }
    if(string1=='b')
        {adder = 2 + adder ; }
    if(string1=='n')
        {adder = 5 + adder ; }
 }

 System.out.println(adder);

你不是在循环中添加你只会得到最后一个字符的值。

试试这种方式

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.HashMap;

public class Test {


    /*final static int a = 1, b = 2, c = 3, d = 4, e = 5, f = 8, g = 3, h = 5,
            i = 1, j = 1, k = 2, l = 3, m = 4, n = 5, o = 7, p = 8, q = 1,
            r = 2, s = 3, t = 4, u = 6, v = 6, w = 6, x = 5, y = 1, z = 7;*/

    public static void main(String[] args) throws IOException {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        String userInput = (in.readLine()).toLowerCase();

        HashMap<Character,Integer> hm = new HashMap<Character, Integer>();

        hm.put('a', 1);     hm.put('b', 2);     hm.put('c', 3);     hm.put('d', 4);     hm.put('e', 5);
        hm.put('f', 8);     hm.put('g', 3);     hm.put('h', 5);     hm.put('i', 1);     hm.put('j', 1);
        hm.put('k', 2);     hm.put('l', 3);     hm.put('m', 4);     hm.put('n', 5);     hm.put('o', 7);
        hm.put('p', 8);     hm.put('q', 1);     hm.put('r', 2);     hm.put('s', 3);     hm.put('t', 4);
        hm.put('u', 6);     hm.put('v', 6);     hm.put('w', 6);     hm.put('x', 5);     hm.put('y', 1);
        hm.put('z', 7);

        int total = 0;

        for(int ai=0;ai<userInput.length();ai++){
            total+= hm.get(userInput.charAt(ai));
        }

        System.out.println(total);
    }

}
