Statements
Figure 136. Statements: General syntax 
Statement's body terminated by “;”
{statement};Figure 137. Statement examples: Declaring and assigning variables
- Variable declaration:
int a;- Value assignment:
a = 33;- Combined declaration and assignment:
int a = 33;
Figure 138. Expression vs. statement
- Expression:
a - 4- Statement:
b = a - 4;Notice the trailing “
;”.
Figure 139. Multiple statements per line
a = b + 3; b = a - 4;Discouraged by good coding practices:
-
Poor readability
-
Hampers debugging

Figure 141. Blocks
double initialAmount = 34;
{ // first block
final double interestRate = 1.2; // 1.2%
System.out.println("Interest:" + initialAmount * interestRate / 100);
}
{ // second block
final double interestRate = 0.8; // 0.8%
System.out.println("Interest:" + initialAmount * interestRate / 100);
}
