Predict the Output of the given snippet, when executed:

int a=1,b=1,m=10,n=5; 
if((a==1)&&(b==0))
{
System.out.println((m+n)); 
System.out.println((m—n));
}
if((a==1)&&(b==1))
{
System.out.println((m*n)); 
System. out.println((m%n));
}

Predict the Output of the given snippet, when executed:

int b=3,k,r;
float a=15.15,c=0;
if(k==1)
{
r=(int)a/b;
System.out.println(r);
}
else
{
c=a/b; 
System.out.println(c);
}

Predict the Output of the given snippet, when executed:

switch (opn)
{
case 'a':
System.out.println("Platform Independent"); 
break;
case 'b':
System.out.println("Object Oriented");
case 'c':
System.out.println("Robust and Secure"); 
break;
default:
System.out.println("Wrong Input");
}

When (i) opn = 'b' (ii) opn = 'x' (iii) opn = 'a'
