Para uma string você entra assim

str = JOptionPane.showInputDialog("Digite algo")

JOptionPane.showMessageDialog(null, "String nome" + str, "Teste")

Aí vai um exemplo simples:

import java.io.*;

public class Ex1 {
	public static void main(String args[]) {
  InputStreamReader entrada = new InputStreamReader(System.in);
  BufferedReader br = new BufferedReader(entrada);
  String valorstr = "";
  System.out.print("Digite o texto: ");
  try {
  	valorstr = br.readLine();
  	System.out.println("Você digitou: " + valorstr);
  catch (Exception e) {
  	System.out.println("Erro: " + e.getMessage());
