Distinguish between Character and Boolean literal

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

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

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);
