Question

hey guys this is my problem..

I want to generate random letters in an specific length of a word, but the Starting Letter should corresponds to value of the variable I declare.

Example:

• A3 should generate AER
• A5 should generate AJIEH
• B2 should generate BJ

Answer 1

Working with the variable names will be tedious (although it is possible I suppose through reflection). You could, however, try something like this:

public static String genString(char first, int len) {
    String s = "";
    for (int i = 1 ; i < len ; i++)
        s += (char)(Math.random() * ('Z' - 'A' + 1) + 'A');
    return first + s;
}

For example:

System.out.println(genString('A', 4));

Output (one of many possible):
