Distinguish between Character and Boolean literal

Explain the term type conversion. How is implicit conversion different from explicit conversion?

In what way is static initialization of data type different from dynamic initialization?

Predict the return data type of 'r' and 'n' from the snippet:

int p; float m;
r = p+m;
n = m/3*(Math.pow(4,3));
System.out.println(r);
System.out.println(n);
