Check if a field is true or false with reflections in java

Currently trying to code some menu functionality and wondered if there’s a way to find out if a boolean field is true or false. This is the code I’m currently trying but I get an error

try{
  
     field = a.getClass().getField(b); 
    
     if(toggle==1&&field){
     }else if(toggle==1&&!field){
       field.set(a, true);
     }else if(toggle==0&&!field){
     }else if(toggle==0&&field){
       field.set(a, false);
     }
}catch (NullPointerException e) {
}catch (NoSuchFieldException e) {
}catch (IllegalAccessException e) {
}

The error is

The operator && is undefined for the argument type(s) boolean, Field

You need to get the value of the field based on an instance.

boolean value = field.getBoolean(instance);

a.getClass().getField(b); return java.lang.reflect.Field;, not a boolean type.

You could use field.getBoolean(a) which get a boolean value.

Class.getField(String) returns a java.lang.reflect.Field. You will want to call getBoolean with that a as an argument. Note that you are assuming that the field is public, which probably isn't a great idea. Also reflection is usually a really bad idea.
