Learn Java for free with this interactive course, and get a handle on one of the most popular programming languages in the world.

You'll start with a simple hello world program and proceed to cover common concepts such as Conditional Statements, Loop Statements, Math, and Logic in Java, before moving on to more advanced concepts like Inheritance, Generics, and ArrayLists, along with much more.

By the time you're done, you'll be an intermediate level Java developer, ready to take on your own projects.

Which of the following evaluates to true? 

Which of the following evaluates to true?

If `x=10`, `y=20`, the what will the following code display?

```java
if (x>y){
   System.out.println("x is greater than y");
   }
else if(x==y){
	System.out.println({"x is equal to y");
	}
else{
	System.out.println("x is less than y");
	}
```

If <code>x=10</code>, <code>y=20</code>, the what will the following code display?
<pre><code class="language-java">if (x&gt;y){
 System.out.println(&quot;x is greater than y&quot;);
 }
else if(x==y){
	System.out.println({&quot;x is equal to y&quot;);
	}
else{
	System.out.println(&quot;x is less than y&quot;);
	}
</code></pre>

What will the following code display? 

```java
int x = 2;
switch (x) {
  case 1:
  case 2:
    System.out.println("First statement");
    break;
  case 3:
    System.out.println("Second statement");
  break;
  case 4:
    System.out.println("Third statement");
  default:
    System.out.println("Default statement");
    break;
}       
```

What will the following code display?
<pre><code class="language-java">int x = 2;
switch (x) {
 case 1:
 case 2:
 System.out.println(&quot;First statement&quot;);
 break;
 case 3:
 System.out.println(&quot;Second statement&quot;);
 break;
 case 4:
 System.out.println(&quot;Third statement&quot;);
 default:
 System.out.println(&quot;Default statement&quot;);
 break;
} 
</code></pre>

What is the output of the following code?
```java
int answer;
int x=10, y=15;
answer= (x>=y)?(x+y):(x-y);
System.out.println("Answer: " + answer);
```

What is the output of the following code?
<pre><code class="language-java">int answer;
int x=10, y=15;
answer= (x&gt;=y)?(x+y):(x-y);
System.out.println(&quot;Answer: &quot; + answer);
</code></pre>
