Wrapper class Boolean constructor work very different. It will only return true if you provide these types of argument:
"true", "TRUE", "True" , "TrUE", "tRUe" etc. all these combinations will return true every thing else will be false. 

### Example:

```
class Main{
	public static void main(String ... args){
		Boolean b1= new Boolean("true");
		Boolean b2= new Boolean("True");
		Boolean b3= new Boolean("TRUE");
		Boolean b4= new Boolean("TrUe");
		Boolean b5= new Boolean("tRUe");
		System.out.println(b1+" "+b2+" "+b3+" "+b4+" "+b5);
	}
}

```
> Output:  true true true true true

Everything else will be false

### Conclusion: 

Boolean b1= new Boolean("false"); //b1=false

Boolean b2= new Boolean("#EP7"); //b2=false

System.out.println(b1.equals(b2)); //true
