The Mystery of life

Tugas Java 1

a. Keyword break

public class BreakBerlabel {
public static void main(String[] args) {
int i = 0, j = 0;

selesai:
while (i <>
j = 0;
while (j <>
if (j == 3)
break selesai;

System.out.println("i = " + i +
" j = " + j);
j++;
}

i++;
}
}
}

output :
i = 0 j = 0
i = 0 j = 1
i = 0 j = 2

b. Keyword continue

public class PernyataanContinue {
public static void main(String[] args) {
int i = 0;

while (i <>
if (i == 3){
i++;
continue;
}

System.out.println(i);
i++;
}
}
}

output :
0
1
2
4

c. keyword return

public class Main {

public static int menghitung(int x)
{
x+=5; // variabel metode
return x;
}

public static void main(String[]args)
{
int x=0;
System.out.println(menghitung(x));
}
}

output :
5

d. Keyword class

public class Main {
public static void menghitung(int x)
{
x+=5; // variabel metode
}

public static void main(String[]args)
{
int x=0;
menghitung(x);
System.out.println(x); // hasilnya 0
}
}

output :
0

e. Keyword Method (Setter & Getter)

class Angka {
private int nilai;

public int getNilai() {
return nilai;
}

public void setNilai(int nilai){ r
this.nilai = nilai;
}

}
class cobaangka{
public static void main(String[] args){
Angka DuaPuluh = new Angka();
DuaPuluh.setNilai(20);
System.out.println(“yang muncul adalah”+DuaPuluh.getNilai());
}
}

Output:
yang muncul adalah 20
