In Java, you will see methods like <code>valueOf</code> and <code>parseInt</code> or <code>parseBoolean</code>. 
<pre><code>
Boolean var = Boolean.valueOf("true");

Boolean var = Boolean.parseBoolean("true");
</code></pre>Why we have these kind of duplicate methods? 
There is a difference in these methods. 
<code>Boolean.valueOf</code> returns a boxed object and not the primitive data type variable. 
<code>Boolean.parseBoolean</code> returns a primitive data type and avoids creating unnecessary object. 
If you have a string value of the variable and need to return a primitive data type, then use <code>parse</code> method. Avoid using <code>valueOf</code>. This will not create unnecessary objects.

In Java, you will see methods like `valueOf` and `parseInt` or `parseBoolean`. 

```

Boolean var = Boolean.valueOf("true");

Boolean var = Boolean.parseBoolean("true");

```

Why we have these kind of duplicate methods? 

There is a difference in these methods. 

`Boolean.valueOf` returns a boxed object and not the primitive data type variable. 

`Boolean.parseBoolean` returns a primitive data type and avoids creating unnecessary object. 

If you have a string value of the variable and need to return a primitive data type, then use `parse` method. Avoid using `valueOf`. This will not create unnecessary objects.
