Post and Pre Increment Operators

[Lomanu4]

Notes1:


package IncrementOperators;

public class Post {
public static void main(String[] args) {
int no = 1;
no = no+1; //no+=1 --> no++;
System.out.println(no); //2

}
}

output:
2

Notes2:


package IncrementOperators;

public class Post2 {
public static void main(String[] args) {
int no = 1;
System.out.println(no++); //no = no+1; Post Increment Operator
System.out.println(no); //2

}
}

output:
1
2

Notes3:


package IncrementOperators;

public class Post3 {
public static void main(String[] args) {
int no = 1;

System.out.println(no--);
System.out.println(no);

}
}

output:
1
0

Notes4:


package IncrementOperators;

public class Post4 {
public static void main(String[] args) {
int no = 10;
System.out.println(no++ + no);

}
}

output:
21

Notes5:


package IncrementOperators;

public class Post5 {
public static void main(String[] args) {
int no = 1;
while(no<=5)
{
System.out.println(no);
no++;
}
}

}

output:
1
2
3
4
5

Notes6:


package IncrementOperators;

public class Pre {
public static void main(String[] args) {
int no = 1;

System.out.println(++no); //no = no+1; Pre Increment Operator
System.out.println(no); //2

}

}

output:
2
2

Notes7:


package IncrementOperators;

public class Pre2 {
public static void main(String[] args) {
int no = 1;

System.out.println(--no); //no = no+1; Pre Increment Operator
System.out.println(no); //2

}
}

output:
0
0

Notes8:


package IncrementOperators;

public class Pre3 {
public static void main(String[] args) {
int no = 1;
while(no<=5)
{
System.out.println(no);
++no;
}
}

}

output:
1
2
3
4
5

Notes9:


package IncrementOperators;

public class Pre4 {
public static void main(String[] args) {

for(int no=1; no<=5; ++no)
System.out.println(no);
}
}

output:
1

Notes10:


package IncrementOperators;

public class PrePost {
public static void main(String[] args) {
int no = 10;
//System.out.println(no++ + no++ + ++no + ++no + no-- + --no);
System.out.println(no++);
System.out.println(no++); //11++
System.out.println(++no); //13
System.out.println(++no); //14
System.out.println(no--); //14
System.out.println(--no); //12
}
}

output:
10
11
13
14
14
12

Notes11:


package IncrementOperators;

public class PrePost2 {
public static void main(String[] args) {
int no1=10, no2=20;
System.out.println(no1++ + no2++ + no1-- + no2-- - --no1 - --no2);
System.out.println(no1++); //10
System.out.println(no2++); //20
System.out.println(no1--); //11
System.out.println(no2--); //21
System.out.println(--no1); //9
System.out.println(--no2);//19
}
}

output:
34

Notes12:


package IncrementOperators;

public class PrePost3 {
public static void main(String[] args) {
int no = 1;
while(no<=5) //2<=5
{
no++;
System.out.println(no);//2
++no;
}
}
}

output:

Task:


package Array;

public class EbBill {
public static void main(String[] args) {
int[] marks = {200,600,300,700,500};
int max = 0;
for(int i=0; i<marks.length; i++)
{
if(marks>max)
max = marks;
}
System.out.println(max);
}
}

output:
700
