Which of the below is NOT a buzz of JAVA

• Portable

• Robust

• Functional

Match the following?

1. A. JDK 1. An abstract machine that executes bytecode

2. B. JRE 2. A software development kit that provides necessary tools for development java code

3. C.JVM 3. Java Runtime Execution

• B-1, C-2, A-3

• A-2, B-3,C-1

• A-1,B-2,C-3

• A-2, C-1, B-3

Portability is achieved by JAVA using

• JVM

• JDK

• JRE

• I dont know

int j=50;

while(true)

{

if(j<10){

break;

}

j=j-10;

}

System.out.println("j is "+j);

• 0

• 10

• 20

• 50

x=1;

y=1;

if(n>0)

x=x+1;

y=y-1;

• x=1, y=1

• x=0,y=2

• x=2,y=1

• x=2,y=0

What is the effect of below conversion

double x;

int a = (int) x;

• No Effect

• Data loss

• Compilation Error

• None of the above
