Contoh-Contoh Program Java beserta Outputnya

1.Keyword Break

class TugasBreak{
public static void main(String[] args){
int i=10;
System.out.println("Before while");
while(i>=0){
System.out.println("Nilai i: "+i);
if(i==5) break;
i--;
}
System.out.println("After while");
}
}

Output :

Before while
Nilai i : 10
Nilai i : 9
Nilai i : 8
Nilai i : 7
Nilai i : 6
Nilai i : 5
After while


2.Keyword Continue

class TugasContinue{
public static void main(String[] args){
int x;
for(x=0;x<10;x++) {
if(x==3) continue;//statement untuk diabaikan
System.out.println("Nilai x:"+x);
if(x==6) break;
}
}
}

Output:

Nilai x : 0
Nilai x : 1
Nilai x : 2
Nilai x : 4
Nilai x : 5
Nilai x : 6

3.Keyword Return

class Return {
public static void main(String args[]) {
boolean t = true;
System.out.println("Sebelum return.");
if(t) return; // return to caller
System.out.println("Tak akan dieksekusi.");
}
}
Output :

Sebelum return

4.Class

class KaliBagi{
public static void main(String[] args) {
int x,y;

//220/2 = 220 >> 1
x = 220 >> 1;
System.out.println("220 / 2 = "+x);

//220*2 = 220 << 1
y = 220 << 1;
System.out.println("220 x 2 = "+y);
}
}

Output :

220 / 2 = 110
220 x 2 = 440


5.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(“Angka yang muncul adalah”+DuaPuluh.getNilai());
}
}

Output:
Angka yang muncul adalah 20
