I don't know how to solve this problem

Here is the copy and pastable version: import java.util.ArrayList; public class Driver { public static void main( String args [] ) { ArrayList binary = new ArrayList(); boolean okay = true; do { okay = true; System.out.print( "Input Number Type(dec/hex/bin): " ); String inputType = SavitchIn.readLine(); if( inputType.equals("hex") ) { System.out.print("Input Number = "); binary = Calculator.hexToBin( SavitchIn.readLine() ); System.out.println( "dec= " + Calculator.binToDec( binary ) ); System.out.print( "bin= " ); int h = 0; while( binary.get(h) == 0 ) h++; for( int k = h; k 9. Write a program that converts from: dec to hex bin hex to dec bin bin to hex/dec import java.util.ArrayList; public class Driver public static void main(String args[]) ArrayList binary = new ArrayList: boolean okay = true; okay = true; System.out.print("Input Number Type(dec/hex/bin): "); String inputType = SavitchIn.readLine(): if( inputType.equals("hex")) System.out.print("Input Number = "); binary - Calculator.hexToBin( Savitchin.readLine()); System.out.println("dec" + Calculator.binToDec( binary ) ); System.out.print("bin= " ); int h = 0; while( binary.get(h) - 0) h++; for( int k = h; k
