Answer 1

public static void main(String[] args) {
    int binary = 0B10110011;
    int octal = 0765;
    int decem = 9864;
    int hex = 0xA54B;
    float f = 89.72F;
    double d = 789.23;
    char c1 = '&';
    char c2 = '*';
    char c3 = 'n';
    char c4 = ' ';
    String str = "java is a language";
    boolean b = false;
    System.out.println(Integer.toBinaryString(binary));
    System.out.println(Integer.toOctalString(octal));
    System.out.println(decem);
    System.out.println(Integer.toHexString(hex));
    System.out.println(f);
    System.out.println(d);
    System.out.println(c1);
    System.out.println(c2);
    System.out.println(c3);
    System.out.println(c4);
    System.out.println(str);
    System.out.println(b);
