Question

•Use Java to rewrite the following code segment using a switch statement. Do not optimize the code, just do a direct translation to switch statement:

if ((k == 1) || (k == 2)) j = 2*k -1

if ((k==3) || (k==5)) j=3*k+1

if (k==4) j=4*k-1

if ((k==6) || (k==7) || (k==8)) j=k-2

Answer 1

if ((k == 1) || (k == 2)) j = 2*k -1
switch(k){
    case 1:
    case 2:
        j = 2*k -1;
        break;
    case 3:
    case 5:
        j=3*k+1;
        break;
    case 4:
        j=4*k-1;
        break;
    case 6:
    case 7:
    case 8:
        j=k-2;    
}
