Trim( )

Question

which one gives output as true?If("string”.trim()==“string”)
If(" string”.trim()==“string”)
If("string ”.trim()==“string”)

Answer 1

I have told you that there are syntax errors in code. I just copy & paste it in Playground and I got error message. If you noticed what I said and fix the problem, you can also easily find the true answer in Playground.

Hint: Use of `equals` yields true for all three expressions. So there bro Indian ...

Answer 2

Your code have syntax errors.
1. The quotes for the string is not regular double quote character.
2. Your `if` statement uses uppercase letter 'i'.
3. You should use `equals` method to check for string equality rather than == or != operator.

Answer 3

Ok ok

and equals() i know ,ofcourse it compares string Data Ipang

You already know about == and `equals`. So your post here is a sort of way to test others. Is that it bro Indian ?

//1.if
if (s==s5)
{
System.out.print("'string'=='string' ");
System.out.println(s==s5);
}
//2.if
if(s==s5.trim())
{
System.out.print("'string'=='string.trim()' ");
System.out.println(s==s5.trim());
}
//3.if
if (s==s1.trim())
{
System.out.println("true");
}
else {System.out.print("'string'==' string.trim()' ");
System.out.println(s==s1.trim());
}
//4.if
if(s==s2)
{
System.out.println("true");
}
else {
System.out.print("s==s2 is ");
System.out.println(s==s2);
}
//5.if
if(s==s4)
{
System.out.println("true");
}
else{ System.out.print("s==s4 is ");
System.out.println(s==s4);
}
