how not to repeat the same record after spaces

Question

This code repeats the output after triple spaces. I just want triple spaces after a word, but the output keeps repeating. For example, I just want to see Output: .- (triple spaces) .-;

String english = input.nextLine();
char[] toChar = english.toCharArray();
String output = "";

for (int i = 0; i < toChar.length; i++) {
    if (toChar[i] == 'a' || toChar[i] == 'A') {
        output += ".-";
    }
    if (toChar[i] == 'b' || toChar[i] == 'B') {
        output += "-...";
    }
    if (toChar[i] == ' ') {
        output += "   ";
    }
    System.out.print(output + " ");
}

Input

a a

Output

.- .-    .-   .-

您的帖子太混乱了。尝试对以后的帖子更加清楚。但是，由于输出在循环内（对输入数据的每个字符重复），因此将重复输出。因此，将您的System.out(....);外部循环。

String english = input.nextLine();
char[] toChar = english.toCharArray();
String output = "";

for (int i = 0; i < toChar.length; i++) {
    if (toChar[i] == 'a' || toChar[i] == 'A') {
        output += ".-";
    }
    if (toChar[i] == 'b' || toChar[i] == 'B') {
        output += "-...";
    }
    if (toChar[i] == ' ') {
        output += "   ";
    }
}
System.out.print(output + " ");
