Can the following conversions involving casting be allowed? If so, find the converted result:

EX 1:

Part a: Can the following conversions involving casting be allowed? If so, find the converted result:

char c = ‘A’;

i = (int)c;

float f = 1000.34f;

int i = (int)f;

double d = 1000.34;

int i = (int)d;

int i = 97;

char c = (char)i;

Part b: Show the output of the following statements:

System.out.println("1" + 1);

System.out.println('1' + 1);

System.out.println("1" + 1 + 1);

System.out.println("1" + (1 + 1));

System.out.println('1' + 1 + 1);

Part c: Show the following output:

float f = 12.5F;

int i = (int)f;

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

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