Question

I’ve a string value String str="Success"

How to check the “str” value is not equal to “Success”. If I try if(str!="Success"). It is not working properly.

I’ve a integer value int a=250 If I use If(a!=250) this is also not working properly.

How to code for these conditional statements ? I’m using Android and Eclipse version 2.1.

Any help would be appreciable.

Answer 1

As every one said, String values should compare with .equals method.

like

if(str.equals("Success"))
{
    System.out.println("My String is Success");
}

Next coming to integer comparison.

As you have said, you have the integer value

int a=250

if(a!=250)
{
   // Some code
}

Here already your a value is 250. then you are executing some lines of code if a value is not equal to 250. Then how the condition will execute. if you want to test then

change the a value and then check again as

int a=50

if(a!=250)
{
   // Some code===============> Now this code will execute
}
