How to use string expression in IF condition Apex

Hi there,
I am stuck in my program, Actually I want to use String expression into the IF statement condition.
eg: 
String expression1 = 'Annual_Rev__c != 0 && Status__c == "Closed"';
if(expression1 ){
System.debug('It Worked...!');
}

Is there any solution for this, Please let me know your thoughts on this.

Thanks,
Rahul​​​​​​​

Hi Anime,

What is the value you are trying to keep in expression1?

below is the if condition check for string.
If(!IsEmpty(expression1 ))

Hi Anime Lover,

As I can see you are passing string value in if condition, but If-else only accepts boolean value.
So, please try the given code below. 
String expression1 = 'Annual_Rev__c != 0 && Status__c == "Closed"';
    if(boolean.valueof(expression1)){
        system.debug('true');
    }else{
        system.debug('false');
    }

I hope you find the above solution helpful. If it does, please mark it as Best Answer to help others too.

Thanks and Regards,

for(Account acc : [select Id,name,Industry from Account where Id ='0012i00000cPzwg']){
    String condition = 'acc.Industry == \'Energy\'';
    System.debug('-> '+Boolean.valueOf(condition));
}

I have set above account Industry value to Energy but I am always getting FALSE value to my debug state ment

Hi  Ankaiah  
usually, we use any Boolean expression in the if(Condition)  like If(Acc.Industry == 'Software') but can we put the condition into the string variable and use that variable to IF() condition like

String expression1 = 'Acc.Industry == 'Software';
if(expression1){
System.debug(true);
}
