我想在代码中显示我的姓名缩写。例如,如果我的名字是Donald Trump
,程序应该写D.T
。
我如何以最简单的方式做到这一点?
package pack_prov;
import javax.swing.*;
public class Filip_Degeryd_uppgift_3 {
public static void main(String[] args) {
String f;
String e;
f = JOptionPane.showInputDialog("first name ");
e = JOptionPane.showInputDialog("last name ");
JOptionPane.showMessageDialog(null, "initials " + f + e + "is" +
f.charAt(0) + ".") + e.charAt(0);
}
}
答案 0 :(得分:0)
下面:
public class Test {
public static void main(String[] args) {
Scanner scn = new Scanner(System.in);
System.out.println("Enter First Name:");
String frstNme = scn.nextLine();
System.out.println("Enter Last Name:");
String lstNme = scn.nextLine();
System.out.println("Your Name Initial Is: " + frstNme.substring(0, 1) + "." + lstNme.substring(0, 1) + ".");
scn.close();
}
}
