Which of the following statement is an example for explicit typecasting?

1. int amount = 45;
2. int amount = 24*24;;
3. int amount = Integer.parseInt("45")
4. int amount = (int)45.75;

The output of the statement Math.ceil.(89.9) + Math.floor(90.5) is:

1. 0.0
2. 180
3. 180.0
4. 180.4

Choose the statement which is equivalent to the given:

if(a>b) 
System.out.println("Honest"); 
else 
System.out.println("Sincere");

1. a>b? System.out.println("Honest"):System.out.println("Sincere");
2. System.out.println(a>b? "Honest":"Sincere");
3. a>b? "Honest": "Sincere";
4. a>b: "Honest"? "Sincere";

The two Java statement are used to check for the equality of the strings "COP" and "cop" are as follows:

"COP".equals("cop") 
"COP".equalsIgnoreCase("cop")

The output of the above statements is:

1. false, true
2. true, false
3. false, false
4. true, true
