A solution would solve several problems that your code has.

i is the index, it should serve to get each character of the word like this:

 frase.charAt(i)

odd and even positions must be obtained, divide the index / 2 and check if it equals 0

import java.util.*;
import java.lang.*;

class MinMayus {
  public static void main(String args[]) {
    String frase = "Que todo fluya y que nada influya";
    int largo = 0;
    largo = frase.length();
    for (int i = 0; i < largo; i++) {
      if (i % 2 == 0) {
        System.out.print((frase.charAt(i) + "").toUpperCase());
      } else {
        System.out.print((frase.charAt(i) + "").toLowerCase());
      }
    }
  }
}
