Map Constructor

public class TEST {
Map<Integer, String> m1 = new Map<Integer, String>();
m1.put(1, 'First item');
m1.put(2, 'Second item');

}
Why do I get this error: Expecting Right Parenthesis found '1'  ??

Hi Adelchi,

This is because you didn't include it in method. Refer following code.
  
public class TEST {

    public static void firstMethod(){
        Map<Integer, String> m1 = new Map<Integer, String>();
        m1.put(1, 'First item');
        m1.put(2, 'Second item');
    }
}

Mark this as solve and choose best answer if your issue resolved.

You are adding code directly to a class instead create a constructor and try again.

public class TEST {
    
   //constructor
    public TEST(){
        Map<Integer, String> m1 = new Map<Integer, String>();
        m1.put(1, 'First item');
        m1.put(2, 'Second item');
    }
}

Thanks, I thought I can use Map<> as class variable, so it can be used by all methods.

Ok so in that case you can do either way.

public with sharing class TEST {
    Map<Integer, String> m1 = new Map<Integer, String>{1=>'First item',2=>'Second item'};
}

OR


public with sharing class TEST {
    Map<Integer, String> m1 = new Map<Integer, String>();
    //Constructor
    public TEST(){
        m1.put(1, 'First item');
        m1.put(2, 'Second item');
    }
}


Please mark this as resolved if this suffice.

Thanks

Ignore with sharing in my example.

Hi Adelchi,

In this case, refer following code,
  
public class TEST {
    public static Map<Integer, String> m2 = new Map<Integer, String>{};
    public static void firstMethod(){
        Map<Integer, String> m1 = new Map<Integer, String>();
        m1.put(1, 'First item');
        m1.put(2, 'Second item');
    }
}
