Java Java Objects (Retired) Creating the MVP Comparing Characters

I keep getting a bummer message that reads: When a "Z" name is entered line 2 is expected but not received.

My boolean getInLine looks like it will be false when lastName.charAt(0) is a number higher in the alphabet (m-z) than "M" because "Z" (26) is <= "M"(13) is false.

Then my if statement says if getInLine is= true then line=1 and if it is false then line=2.

Because in this case is a "Z" name is used boolean should be false and and then the if statement should return line=2. Is my issue with defining the getInLine incorrectly or using the if statement incorrectly? Or is my issue related to what I have in the return line?

ConferenceRegistrationAssistant.java
public class ConferenceRegistrationAssistant {

  public int getLineFor(String lastName) {
    /* If the last name is between A thru M send them to line 1
       Otherwise send them to line 2 */
    boolean getInLine = lastName.charAt(0) <= 'M';
    int line;
    if (getInLine = true) {
      line =1; 
    } else {
      line = 2;
    }
    return line;
  }

}

The problem is the line if (getInLine = true) which is assigning getInLine to true (single vs. double equal signs). It's usually redundant to compare a boolean to true or false in an if statement and just use if (getInLine).

Simpler to do this code, because method returns int.

char a_char = text.charAt(0);

if ( a<='A' && a<='M'){ // the greater the letter the higher the value Z being the biggest value line=0; }else{ line=1; } return line;
